To build a real app — even the todo\nStarter — a consumer needs text, layout, form, and container primitives. Without\nthem they drop to raw HTML styled with hand-written Twind, which reintroduces\nthe per-app inconsistency Kylä exists to prevent, and loses the bounded\naccessibility guarantees (label association, focus ring, semantic elements) that\ncome baked into Kylä components.\n\n## Solution\n\nShip the v1 zero-dependency visual component set plus the one styled-native\ncomponent, each authored exactly like `Button`: typed variant props mapped to\ntokens via `variants()`, a semantic HTML element, forwarded ref + rest props, a\ntoken-based visible focus ring where interactive, an escape-hatch `className`\nmerged last via `cn()`, and ADR-0003's bounded accessibility baseline. Spacing\nand type come from the structural scale tokens, so the set is consistent with\nitself and with anything built on top of it.\n\n**Inventory:** `Text`/`Heading`, `Card`, `Input`, `Textarea`, `Label`, `Badge`,\n`Stack`, `Box`, `Divider`, and styled-native `Select` — plus a **revision slice\nfor** `Button`, closing the VT variant/state coverage gap flagged by ADR-0005's\ncoverage-parity clause (the roadmap marks `Button` \"Built,\" but built ≠ at\nparity).\n\n## User Stories\n\n1. As a consumer, I want a `Text` component with typed size/weight/tone props,\n so that body copy uses the type scale without me choosing `text-*` classes.\n2. As a consumer, I want a `Heading` component (or `Text as=\"h1\">`), so that\n headings are semantic and on-scale.\n3. As a consumer, I want a `Card` with surface and padding variants, so that I\n can group content on an elevated surface consistently.\n4. As a consumer, I want an `Input` with a visible token focus ring and disabled\n state, so that text entry looks and behaves on-system.\n5. As a consumer, I want a `Textarea` matching `Input`, so that multi-line entry\n is consistent with single-line.\n6. As a consumer, I want a `Label` that associates with a field via `htmlFor`,\n so that clicking the label focuses the input and screen readers announce it.\n7. As a consumer, I want a `Badge` with typed tones, so that I can show\n status/labels on-system.\n8. As a consumer, I want a `Stack` layout primitive with a direction and a gap\n drawn from the spacing scale, so that I lay out children without hand-writing\n flex + gap classes.\n9. As a consumer, I want a `Box` primitive, so that I have a styled generic\n container with the escape hatch when no semantic component fits.\n10. As a consumer, I want a `Divider`, so that I can separate content with an\n on-system hairline.\n11. As a consumer, I want a `Select` that looks on-system but keeps native\n ``; sizes matching `Input`. VT adds\n `appearance-none pr-10 cursor-pointer` (§5) — match that base styling.\n- **Dependency:** consumes the scale tokens from the\n [scales PRD](../structural-scales-palette/PRD.md). If that lands first,\n components reference scale tokens directly; the spacing/type props map onto\n those steps.\n- **Accessibility (ADR-0003):** real `` ↔ field `id` association;\n correct semantic elements; token visible focus; no broken native keyboard\n behavior; AA contrast inherited from the default palette. Anything needing\n custom ARIA is out — that's the Radix tier.\n- **Public surface unchanged in shape:** finished components + `cn()` +\n Provider. No headless primitives exposed.\n\n## VT Parallelism Audit (ADR-0005 coverage parity)\n\nPer-component record of what the ADR-0005 coverage-parity clause requires: does\na VT counterpart exist, what does it cover, and where does Kylä's plan match,\nintentionally diverge, or have a real gap. Sourced primarily from\n`docs/reference/val-town-style-guide.md` §5 (verbatim `_ui` classes — the\nauthoritative source). Where a component's only VT signal comes from\n`val.town/secret-styleguide` (Val Town's broader internal component library, not\nthe sourced `_ui` reference), that's called out explicitly as informal — that\npage doesn't expose class attributes over a plain fetch, so nothing from it is a\nverbatim spec the way §5's `_ui` entries are.\n\n| Kylä component | VT counterpart | Parity status |\n| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| `Button` | `/_ui/button` | **Gap, tracked** — [ticket 04](issues/04-button-variant-parity.md): 4 of 7 color variants covered, icon-only sizing missing. |\n| `Text`/`Heading` | No componentized VT equivalent; VT's type scale/weights (§4) apply directly. `secret-styleguide`'s \"Page Heading\" is a same-shaped signal (large heading at two sizes) but not a sourced spec. | **No gap to close** — use VT's type-scale steps for `size`/`weight`; there's no VT variant count to match since VT doesn't ship this as a reusable component. |\n| `Card` | `/_ui/card` — in VT's own internal library this is the \"ProjectCard\"/\"BigCard\" family (`secret-styleguide`), i.e. a domain-specific project tile, not a generic container primitive. | **Real mismatch, not a coverage gap.** VT's card is flat `bg-background` + `border`, elevating only via `hover:shadow-lg` + `hover:border-blue-400` (§5) — it never uses a raised or inset _fill_. Kylä's `surface: elevated/recessed` assumes a fill-based hierarchy that has no VT counterpart anywhere. This is ADR-0005's already-recorded intentional divergence (Kylä keeps its own richer surface hierarchy), but it means the component's _default_ rendering, not just its token palette, needs a deliberate call — see the Implementation Decisions bullet above. |\n| `Input`/`Textarea` | `/_ui/input`, `/_ui/textarea` | **Gap:** filled/soft variant and `read-only` treatment (§5) not yet in the pinned surface. |\n| `Label` | No dedicated VT primitive — VT associates labels inline within its field markup rather than shipping a standalone component. | **No gap to close** — Kylä's standalone `Label` is a Kylä-only primitive (needed because Kylä's components are more granular than VT's field markup), not a port. |\n| `Badge` | No generic VT Badge. `/_ui/privacy-badge` is a narrow, product-specific analog (public/private/unlisted only). `secret-styleguide`'s \"Tag\" (5 states: neutral/danger/positive/warning/fun, at 3 sizes) is the closer _conceptual_ analog but isn't a sourced spec. | **No gap tracked here** — tone set stays a Kylä design call. If revisited later: `positive` would map onto the already-landed `success` token; `warning`/`fun` have no home in Kylä's current token vocabulary and shouldn't be invented ad hoc inside a component PRD. |\n| `Stack`/`Box`/`Divider` | No VT primitive equivalent. `secret-styleguide`'s \"Bento layout system\" is the nearest signal (a product-layout grid for arranging project cards), not a reusable primitive. | **No gap to close** — Kylä-only design calls, same reasoning as `Badge`. |\n| `Select` | `/_ui/select` | **Gap:** `appearance-none pr-10 cursor-pointer` (§5) not yet in the pinned surface. |\n\nTakeaway: three components (`Text`/`Heading`, `Label`, `Stack`/`Box`/`Divider`)\nand `Badge` have no VT surface to port at all — that's a legitimate parity\nverdict, not an unaudited hole. `Card` is the one case where \"port VT's values\"\nand \"keep Kylä's structure\" actively pull in different directions and needs an\nexplicit default decision, not just a token mapping.\n\n## Testing Decisions\n\n- **What makes a good test:** it asserts the component's _external_ output and\n behavior — the rendered element, the token classes it emits, and its\n accessibility wiring — never the internal `variants()`/`cn()` call. Testing\n the emitted class string via the rendered HTML also guards the silent Twind\n \"missing `color:` hint\" failure, since a dropped hint shows up as an absent\n token class.\n- **Seam (highest available):** **server-render the component to an HTML\n string** (`renderToStaticMarkup`) and assert on the markup. Uniform across the\n set.\n - Assert the semantic element (``, `

`, `<select>`, `<hr>`,\n    heading tags for `Heading`).\n  - Assert token utility classes are present for the chosen variant/tone (e.g.\n    `Badge tone=\"danger\"` emits `bg-[color:var(--kyla-danger)]`).\n  - Assert accessibility wiring: `Label htmlFor` matches an `Input id`; `Input`\n    forwards `type`; `disabled`/`aria-invalid` render; the focus-ring classes\n    are present on interactive components.\n  - Assert `className` wins over the component's own conflicting class (the\n    `cn()` contract).\n- **Modules tested:** every component in `src/components/`.\n- **Prior art:** the harness established by the\n  [scales PRD](../structural-scales-palette/PRD.md); if this ships first, it\n  establishes the render-to-HTML harness itself. `Button` is the reference for\n  what a component's rendered output should look like.\n\n## Out of Scope\n\n- `Button` **'s polymorphic rendering** (VT's Router Link / external-link button\n  forms) — needs a Slot-style primitive Kylä doesn't have yet. Flagged by the\n  variant-parity audit, not built here.\n- `Dialog` and any Radix-backed component —\n  [separate PRD](../dialog-radix/PRD.md).\n- v1.1+ deferred components: `Checkbox`, `Radio`, `Spinner`, `Alert`, then\n  `Popover`, `Menu`, `Tabs`, `Tooltip`, `Combobox`, `Toast`, `Table`.\n- The **Gallery** rendering of these components —\n  [separate PRD](../gallery/PRD.md).\n- Defining the scales themselves —\n  [scales PRD](../structural-scales-palette/PRD.md).\n\n## Further Notes\n\n- Building the set will dogfood the scale tokens and likely surface gaps (as\n  `Button` surfaced the state-prefixed token-utility gap). Feed those back into\n  the scales/`tw` layer rather than working around them in a component.\n- Keep each component small enough that the `Button` pattern stays legible; the\n  uniformity is the point.\n","spec.md","# PRD: v1 zero-dependency component set\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n> Builds out the rest of the v1 component inventory (see the\n> [roadmap](../../roadmap.md)), following the `Button` reference.

As a maintainer, I want each shipped component exported from the `mod.ts`\n    barrel, so that consumers import the whole zero-dep core from one URL.\n18. As a maintainer, I want the interactive components (`Input`, `Textarea`,\n    `Select`) to carry the token focus ring, so that the accessibility baseline\n    is uniform.\n19. As an end user, I want inputs and controls to have visible focus and correct\n    labels, so that I can use the app with a keyboard and a screen reader.\n20. As an end user, I want consistent spacing and legible text across the whole\n    app, so that it reads as one coherent product.\n\n## Implementation Decisions\n\n- **Modules built:** one file per component in `src/components/`, each exported\n  from `mod.ts` (the zero-dep barrel). No component in this set pulls a headless\n  dependency — that boundary is `Dialog`'s (ADR-0002).\n- **Authoring contract (from** `Button` **):** `variants()` maps typed props →\n  token classes; semantic element; `forwardRef` + rest props; default-safe\n  attributes (as `Button` defaults `type=\"button\"`); `className` merged last via\n  `cn()`; token focus ring via `tw.ring`/`tw.ringOffset` on interactive\n  elements.\n- **Per-component variant surfaces (pinned here), audited for VT coverage parity\n  (ADR-0005) against** `docs/reference/val-town-style-guide.md` **§5:**\n  - `Button` (**revision**, not net-new — see the dedicated ticket): VT ships 7\n    color variants (`default`/`primary`/`secondary`/`clear`/`danger`/\n    `green`/`blend`) against Kylä's current 4 (`primary`/`subtle`/`ghost`/\n    `danger`). `subtle`≈VT `secondary` and `ghost`≈VT `clear` already; the real\n    gaps are an unbordered filled-neutral variant (VT `default`), a\n    `success`-backed variant (VT `green`), the `mix-blend-mode` `blend` variant,\n    and icon-only sizing (`!px-0 w-8`/`w-10`). Kylä keeps its own prop names\n    throughout — only the _coverage_ is ported, not VT's vocabulary (ADR-0005).\n  - `Text`/`Heading`: `size` (type-scale steps), `weight`, `tone`\n    (`fg`/`fg-muted`/`accent`/`danger`); polymorphic `as` for the element.\n  - `Card`: `surface` (`elevated`/`recessed`), `padding` (spacing-scale steps).\n    **See the VT Parallelism Audit below — this is a structural mismatch, not\n    just a coverage gap:** VT's card has no elevated/recessed fill at all; it's\n    flat + bordered, hovering to `border-blue-400` + `shadow-lg` (§5). Pin\n    `surface`'s _default_ to the flat/bordered treatment (`base`, not\n    `elevated`) so the component reads as VT-native out of the box; keep\n    `elevated`/`recessed` as explicit opt-ins, since `recessed` in particular\n    has zero VT precedent.\n  - `Input` / `Textarea`: sizes matching `Button`; `invalid` state wired to\n    `aria-invalid` and the `danger` token. VT additionally ships a filled/soft\n    background variant and a distinct `read-only` treatment (§5) — cover both.\n  - `Badge`: `tone` set (`neutral`/`accent`/`danger`/… as needed), `size`. See\n    the VT Parallelism Audit below — no generic VT Badge exists to audit\n    against; tone set stays Kylä's own design call.\n  - `Stack`: `direction` (row/column), `gap` (spacing-scale steps), alignment.\n  - `Box`: minimal styled container, no required variants.\n  - `Divider`: orientation, uses the `hairline`/`line` token.\n  - `Select`: styled native `<select>`; sizes matching `Input`. VT adds\n    `appearance-none pr-10 cursor-pointer` (§5) — match that base styling.\n- **Dependency:** consumes the scale tokens from the\n  [scales PRD](../structural-scales-palette/spec.md). If that lands first,\n  components reference scale tokens directly; the spacing/type props map onto\n  those steps.\n- **Accessibility (ADR-0003):** real `<label htmlFor>` ↔ field `id` association;\n  correct semantic elements; token visible focus; no broken native keyboard\n  behavior; AA contrast inherited from the default palette. Anything needing\n  custom ARIA is out — that's the Radix tier.\n- **Public surface unchanged in shape:** finished components + `cn()` +\n  Provider.

Where a component's only VT signal comes from\n`val.town/secret-styleguide` (Val Town's broader internal component library, not\nthe sourced `_ui` reference), that's called out explicitly as informal — that\npage doesn't expose class attributes over a plain fetch, so nothing from it is a\nverbatim spec the way §5's `_ui` entries are.\n\n| Kylä component          | VT counterpart                                                                                                                                                                                                                                                     | Parity status                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |\n| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| `Button`                | `/_ui/button`                                                                                                                                                                                                                                                      | **Gap, tracked** — [ticket 04](issues/04-button-variant-parity.md): 4 of 7 color variants covered, icon-only sizing missing.                                                                                                                                                                                                                                                                                                                                                                                                                                                |\n| `Text`/`Heading`        | No componentized VT equivalent; VT's type scale/weights (§4) apply directly. `secret-styleguide`'s \"Page Heading\" is a same-shaped signal (large heading at two sizes) but not a sourced spec.                                                                     | **No gap to close** — use VT's type-scale steps for `size`/`weight`; there's no VT variant count to match since VT doesn't ship this as a reusable component.                                                                                                                                                                                                                                                                                                                                                                                                               |\n| `Card`                  | `/_ui/card` — in VT's own internal library this is the \"ProjectCard\"/\"BigCard\" family (`secret-styleguide`), i.e. a domain-specific project tile, not a generic container primitive.                                                                               | **Real mismatch, not a coverage gap.** VT's card is flat `bg-background` + `border`, elevating only via `hover:shadow-lg` + `hover:border-blue-400` (§5) — it never uses a raised or inset _fill_.

Testing\n  the emitted class string via the rendered HTML also guards the silent Twind\n  \"missing `color:` hint\" failure, since a dropped hint shows up as an absent\n  token class.\n- **Seam (highest available):** **server-render the component to an HTML\n  string** (`renderToStaticMarkup`) and assert on the markup. Uniform across the\n  set.\n  - Assert the semantic element (`<input>`, `<textarea>`, `<select>`, `<hr>`,\n    heading tags for `Heading`).\n  - Assert token utility classes are present for the chosen variant/tone (e.g.\n    `Badge tone=\"danger\"` emits `bg-[color:var(--kyla-danger)]`).\n  - Assert accessibility wiring: `Label htmlFor` matches an `Input id`; `Input`\n    forwards `type`; `disabled`/`aria-invalid` render; the focus-ring classes\n    are present on interactive components.\n  - Assert `className` wins over the component's own conflicting class (the\n    `cn()` contract).\n- **Modules tested:** every component in `src/components/`.\n- **Prior art:** the harness established by the\n  [scales PRD](../structural-scales-palette/spec.md); if this ships first, it\n  establishes the render-to-HTML harness itself. `Button` is the reference for\n  what a component's rendered output should look like.\n\n## Out of Scope\n\n- `Button` **'s polymorphic rendering** (VT's Router Link / external-link button\n  forms) — needs a Slot-style primitive Kylä doesn't have yet. Flagged by the\n  variant-parity audit, not built here.\n- `Dialog` and any Radix-backed component —\n  [separate PRD](../dialog-radix/spec.md).\n- v1.1+ deferred components: `Checkbox`, `Radio`, `Spinner`, `Alert`, then\n  `Popover`, `Menu`, `Tabs`, `Tooltip`, `Combobox`, `Toast`, `Table`.\n- The **Gallery** rendering of these components —\n  [separate PRD](../gallery/spec.md).\n- Defining the scales themselves —\n  [scales PRD](../structural-scales-palette/spec.md).\n\n## Further Notes\n\n- Building the set will dogfood the scale tokens and likely surface gaps (as\n  `Button` surfaced the state-prefixed token-utility gap). Feed those back into\n  the scales/`tw` layer rather than working around them in a component.\n- Keep each component small enough that the `Button` pattern stays legible; the\n  uniformity is the

styled** web apps on Val Town.\nKylä is Finnish for \"village.\"\n\nMost Val Town apps are assembled fast and without a designer, so they end up\nlooking inconsistent. Kylä gives you opinionated, on-system components so your\napp looks coherent by default. Accessibility (semantic HTML, label association,\nvisible focus, AA contrast) is a quiet guarantee underneath.\n\nBuilt for Val Town's reality: **no build step**. Components are React, styled\nwith runtime [Twind](https://twind.style) + semantic CSS-variable tokens, and\nconsumed by import — no bundler, no codegen.\n\n## Quick start\n\n1. Your HTML shell must load Twind (it has to be present before first paint):\n\n   ```html\n   <script src=\"https://cdn.twind.style\" crossorigin></script>\n   ```\n\n2. Wrap your app in `KylaProvider` (it injects the design tokens and owns\n   light/dark mode), then use components:\n\n   ```tsx\n   /** @jsxImportSource https://esm.sh/react@18.2.0 */\n   import {\n     Button,\n     KylaProvider,\n   } from \"https://esm.town/v/nbbaier/kyla-ui/mod.ts\";\n\n   export function App() {\n     return (\n       <KylaProvider>\n         <Button variant=\"primary\" onClick={() => alert(\"hi\")}>Save</Button>\n       </KylaProvider>\n     );\n   }\n   ```\n\nTo pin a version, append `?v=NNN` to the import URL; the unpinned URL always\ntracks the latest release (see\n[ADR-0004](docs/adr/0004-version-pinned-upgrade-contract.md)).\n\n## Status\n\nEarly. The styling foundation (`cn`, `tw`, `variants`, `KylaProvider`) and the\nfirst component (`Button`) are in place; the rest of the v1 component set and\nthe real design palette are still to come.\n\n## Components\n\n- `Button` — `variant`: `primary | subtle | ghost | danger`, `size`:\n  `sm | md | lg`.\n\n## Project docs\n\n- [`CONTEXT.md`](CONTEXT.md) — the glossary / shared language.\n- [`docs/roadmap.md`](docs/roadmap.md) — the dependency-ordered plan to v1 +\n  status.\n- [`docs/adr/`](docs/adr/) — architecture decision records.\n\nThe substrate (Radix + Twind + tokens + Provider on Val Town) is proven in a\nseparate spike val, `nbbaier/kyla-ui-spike`.\n",[160],"2a2918a9-7e7b-4b9e-a2fe-7d1c29ffdd5c","CONTEXT.md","bce56486-6b46-11f1-8898-1607ee4eb77e",174,["D",1784058609130],5,"# Kylä UI — Context\n\nA glossary of the core terms in this project. Implementation details live in\ncode and ADRs, not here.\n\n> \"Kylä\" is Finnish for \"village.\"\n\n## Glossary\n\n### Kylä UI\n\nThe component library itself: a Val Town val (`nbbaier/kyla-ui`) that exports\nReact components, a styling system, and any helpers needed to build consistently\nstyled web apps. It is **consumed by import**\n(`import { ... } from \"https://esm.town/v/nbbaier/kyla-ui/...\"`), not by\nremixing. This val is the source of truth for visual consistency across apps. It\n**also serves its own Gallery** (docs) at its HTTP route — the library documents\nitself, co-located with its source.\n\n### Starter\n\nA separate, remixable demo val (`kyla-ui-starter` or similar) that shows\nidiomatic _end-to-end_ use of Kylä UI: a tiny but genuine **todo app** with a\nreal HTTP route and `std/sqlite`, a working app shell, Provider + hydration\nwiring, and view-source link. A new app begins by remixing the Starter, then\nediting. The Starter **depends on** Kylä UI; the library never depends on the\nStarter. (Component reference/docs live in the library's Gallery, not the\nStarter.)\n\n### Gallery\n\nThe library's self-hosted documentation surface: an HTTP route on `kyla-ui` that\nrenders every component in its variants and Modes, with the Mode toggle. It is\nboth living docs and the in-browser proof that the stack renders correctly on\nVal Town (Twind + CSS-var tokens, Provider mode, Radix `Dialog` hydration). The\nseed of a fuller docs site later.\n\n### Release\n\nA blessed version of Kylä UI, produced by merging a development branch into\n`main`. `main` is the stable line: raw development never happens on it, so\nHEAD-of-`main` is always a Release. Each Release corresponds to a concrete Val\nTown version number (`?v=NNN`). A consumer tracks Releases by importing the\nunpinned URL (always latest Release) or freezes onto one by pinning its\n`?v=NNN`, which the README's release table maps by name.\n\n### Consumer\n\nA web app (a val) built with Kylä UI. Gets visual consistency by importing the\nlibrary rather than copying its code.\n\n### Semantic Token\n\nA named, intent-based design value (e.g. \"base surface,\" \"default foreground,\"\n\"line/border,\" \"danger\") rather than a raw value (e.g. \"blue-500\"). Components\nreference semantic tokens only; they never hard-code raw colors. Tokens are the\nunit of visual consistency and the surface through which a Theme is applied.\n(Modeled on Cloudflare Kumo's semantic-token system.)\n\nCanonical token vocabulary (CSS custom properties, all prefixed `--kyla-`):\n\n- **Surfaces** (hierarchy): `base` → `elevated` → `recessed`\n- **Foreground:** `fg`, `fg-muted`\n- **Borders:** `line`, `hairline`\n- **Accent:** `accent`, `accent-fg`, `accent-ring`, `accent-text`\n- **Status:** `danger`, `danger-fg`, `success`, `success-fg`\n- **Shape:** `radius`\n\nThe default theme's values conform to the Val Town UI style guide (see\n[ADR-0005](docs/adr/0005-val-town-visual-language-default-theme.md)); Kylä keeps\nits own richer surface hierarchy over VT's palette.\n\nOf these, the consumer-facing Override Surface for v1 is intentionally small\n(e.g. `--kyla-accent`, `--kyla-radius`, font); the rest are structural and stay\nfixed.\n\n### Theme\n\nA complete set of values bound to the Semantic Tokens, producing a coherent\nlook. A consumer switches the active theme without touching component code.\nLight/dark is one axis of theming; brand/variant overrides are another.\n\nFor v1, Kylä ships **one opinionated theme** with automatic light/dark, and\nexposes a deliberately small **Override Surface** — a few tokens (e.g. accent,\nradius, font) a consumer may redefine to express brand. Structural tokens\n(surface hierarchy, spacing, borders) stay fixed; that fixedness _is_ the\nconsistency. A fuller named-theme system (multiple consumer-defined Themes, à la\nKumo's theme configs) is a deliberate later step, not a v1 feature.\n\n### Variant\n\nA named, typed dimension of a component's appearance exposed as a prop (e.g.\n`variant=\"primary\"`, `size=\"sm\"`, `tone=\"danger\"`). Variants map to Semantic\nTokens internally; they are the consumer's primary, discoverable means of\nvarying a component while staying on-system. An escape-hatch `className` always\nmerges last, letting an app deviate locally without forking. For v1 the public\nsurface is finished components plus a `cn()` helper and the Provider — the\nunderlying Headless Primitives stay internal.\n\n### Mode\n\nThe light/dark axis of a Theme. Modeled as\n`data-mode=\"light\" | \"dark\" | \"system\"`, where `system` falls through to the OS\npreference via CSS `light-dark()` (zero JS). Mode is **owned by the Provider** —\nit sets `data-mode` and exposes a hook to read/set it (persistence opt-in) — so\napps get a first-class light/dark toggle without hand-rolling one (a common\nsource of inconsistency and flash-of-wrong-theme bugs).\n\n### Headless Primitive\n\nThe behavior-and-accessibility layer of an interactive component (focus\nmanagement, keyboard nav, ARIA), independent of its visual styling. For the hard\ninteractive components (Dialog, Popover, Menu, Tabs), Kylä builds on a\nthird-party headless primitive library rather than hand-rolling. Simple visual\ncomponents (Button, Card, Stack, Text, Input, Badge) have no separate Headless\nPrimitive — they are styled directly.\n",[168],"16d56331-fa60-4ad6-828c-e4aa90df5d26","CLAUDE.md","a53286c6-775c-11f1-abf2-1607ee4eb77e",209,["D",1784058612706],6,"## Working on changes\n\nDevelopment happens on a Val Town **val branch**, never directly on `main`.\n`main` is the stable release line — HEAD-of-`main` is always a Release (a\nconcrete `?v=NNN`), so raw work never lands on it. Branch off `main`, do the\nwork on the branch, and land it by merging the branch into `main`, which cuts\nthe next Release. See\n[ADR-0004](docs/adr/0004-version-pinned-upgrade-contract.md) for the rationale\nand the consumer-facing pinning contract.\n\n**Exception: docs-only changes push straight to `main`.** Changes confined to\n`docs/**` (PRDs, ADRs, roadmap, reference docs) carry no code/version surface,\nso they don't need a branch + merge cycle — push them directly. Any change that\ntouches `src/`, `mod.ts`, or other shipped code still follows the branch flow\nabove.\n\n## Agent skills\n\n### Issue tracker\n\nIssues and PRDs live as local markdown files under\n`docs/issues/<feature-slug>/`; no external tracker.

Extracted\n2026-07-06.\n\n## What was found, and from where\n\nVal Town's marketing/app site is a **Remix SSR** application, so a plain HTTP\n`GET` of each `https://www.val.town/_ui/<component>` page returns the **real,\nserver-rendered component markup** — every element with its full Tailwind\nutility class list. The token layer lives in the site's compiled Tailwind **v4**\nstylesheet, linked from every page and served from\n`https://static2.esm.town/assets/tailwind-<hash>.css` (current hash at\nextraction time: `tailwind-Dy1Hj0e7.css`). That file contains the Tailwind v4\n`@theme` block (the full `--color-*` scale in **oklch**, plus `--spacing`,\n`--radius-*`, `--text-*`, `--font-weight-*`) **and** Val Town's own semantic\ncolor aliases split across the light `@theme`/`:root` layer and a `.dark {…}`\nblock.\n\n**This is the primary, authoritative source** and it is machine-readable\nend-to-end: component class lists → utility classes → resolved token values, all\nfrom the live site.\n\nA **secondary** source — the val **`dcm31/townie-mobile`**, `frontend/style.css`\n(read via the Val Town MCP `read_file`) — is the distilled token set its author\nhand-fed to Fable. It agrees with the live site on the design _language_\n(slate + sky, IBM Plex Sans, iA Writer Quattro eyebrows, dark-ink-on-accent, 8px\nradius) but its literal hex values are **Tailwind v3** (e.g.\n`--vt-sky: #38bdf8`), which differ numerically from the live site's Tailwind\n**v4** oklch derivations (`sky-400` → `#00bcff`). Reconciliation is called out\nbelow.\n\n### Colour-space note\n\nThe live tokens are **oklch** (Tailwind v4). Every hex in this doc is a\n**computed** oklch→sRGB conversion (D65, standard sRGB transfer). Hexes are\nlabelled as computed; the oklch string is the source-of-truth value. Contrast\nratios are likewise computed from those sRGB values.\n\n### Reconciliation: townie-mobile (v3 hex) vs live `_ui` (v4 oklch)\n\n| Role        | townie `style.css` (v3 literal)         | live `_ui` (v4 oklch → computed hex)                | Agree?                                 |\n| ----------- | --------------------------------------- | --------------------------------------------------- | -------------------------------------- |\n| Accent      | `--vt-sky #38bdf8` (sky-400)            | `sky-400` `oklch(74.6% .16 232.661)` → `#00bcff`    | Same token name; v4 hex more saturated |\n| Deep accent | `--vt-sky-deep #0369a1` (sky-700)       | `sky-700` `oklch(50% .134 242.749)` → `#0069a8`     | Same name, v4 slightly different       |\n| Border      | `--vt-border #e2e8f0` (slate-200)       | `slate-200` `oklch(92.9% .013 255.508)` → `#e2e8f0` | **Identical**                          |\n| Accent-fg   | send btn `text-sky-950` on `bg-sky-400` | primary btn `text-sky-950` on `bg-sky-400`          | **Identical convention**               |\n\nBoth confirm **VT = Tailwind slate + sky**.

Gaps and AA concerns\n\n### Gaps — Kylä tokens with no direct VT semantic equivalent\n\n- **`--kyla-elevated`, `--kyla-recessed`, `--kyla-hairline`:** VT's semantic\n  layer is only `background / text / border / muted / shadow`. There is **no**\n  token for a second surface level. In light mode VT elevates by shadow over the\n  same white; recessed/hairline surfaces come from raw `slate-50`/`slate-100`\n  fills at the component level. The proposed values are the observed component\n  fills, not named VT tokens — reasonable but an extrapolation.\n- **`--kyla-danger-fg` / accent-fg split:** VT expresses \"ink on a colored fill\"\n  per component (dark-950 in light, white in dark) rather than as a token. Also,\n  VT uses several distinct accent roles a single\n  `--kyla-accent`/`--kyla-accent-fg` can't hold: **fill** (`sky-400`/`sky-700`),\n  **focus ring** (`sky-500`, inputs `sky-300`), and **accent text on a surface**\n  (`sky-800` light / `sky-200` dark, used for hover/aria-current). Consider\n  `--kyla-accent-ring` and `--kyla-accent-text` in addition to fill+fg.\n\n### VT tokens/roles Kylä has no home for\n\n- **`--color-shadow`** (gray-50 light / gray-900 dark) — a mode-aware shadow\n  tint; Kylä has no shadow token.\n- **Field border ≠ panel border:** inputs use `slate-300`/`slate-700`, panels\n  use `slate-200`/`slate-700` (`--color-border`). Kylä's single `--kyla-line`\n  flattens this.\n- **Semantic status set beyond danger:** VT ships `emerald` (success/green\n  button, public badge), `amber`/`blue` (callouts), `orange` (unlisted badge).\n  Kylä has only `danger`.\n- **`blend` button** (`mix-blend-color-burn`/`-dodge`) — a mode-adaptive\n  technique, no token.\n\n### WCAG AA (ratios **computed** from oklch→sRGB; 4.5:1 body, 3:1 large/UI)\n\n| Foreground                      | Background                   | Ratio       | Verdict                                                                       |\n| ------------------------------- | ---------------------------- | ----------- | ----------------------------------------------------------------------------- |\n| `text` black                    | `background` white (light)   | **21.0:1**  | Pass AAA                                                                      |\n| `text` white                    | `background` black (dark)    | **21.0:1**  | Pass AAA                                                                      |\n| `muted` gray-600                | white (light)                | **7.56:1**  | Pass                                                                          |\n| `muted` gray-300                | black (dark)                 | **14.26:1** | Pass                                                                          |\n| primary `sky-950`               | `sky-400` fill (light)       | **6.37:1**  | Pass                                                                          |\n| primary white                   | `sky-700` fill (dark)        | **5.86:1**  | Pass                                                                          |\n| default `slate-800`             | `slate-100` fill (light)     | **13.34:1** | Pass                                                                          |\n| default-hover `sky-800`         | `sky-100` (light)            | **6.53:1**  | Pass                                                                          |\n| danger `rose-950`               | `rose-300` fill (light)      | **8.19:1**  | Pass                                                                          |\n| danger white                    | `rose-800` fill (dark)       | **7.92:1**  | Pass                                                                          |\n| green `emerald-950`             | `emerald-400` fill (light)   | **7.83:1**  | Pass                                                                          |\n| `slate-700` (field border/text) | white                        | **10.36:1** | Pass                                                                          |\n| **white**                       | **`sky-400`** (anti-pattern) | **2.18:1**  | **FAIL** — do not put white on the light accent; VT correctly uses `sky-950`. |\n\nTakeaways for Kylä:\n\n1. Every default VT foreground/surface pairing clears AA comfortably (5.9–21:1)\n   in **both** modes — safe to adopt wholesale.\n2. `--kyla-accent-fg` must be **dark ink (`sky-950`) in light** and **white in\n   dark**; a single fixed value can't serve both because `sky-400` needs dark\n   ink (white fails at 2.18:1) while `sky-700` needs white.\n3. `--kyla-fg-muted` = `gray-600` (light) / `gray-300` (dark) is AA-safe; keep\n   the mode split rather than one value.\n4. Note the deliberate **true-black dark background** — visually aggressive\n   (21:1); fine for AA, but worth a conscious call vs a softer\n   `slate-950 #020618` if Kylä prefers less glare.\n\n---\n\n## 8.

This PRD turns\n> the provisional token stylesheet into a real, fixed structural foundation. It\n> is the prerequisite for the [v1 component set](../v1-component-set/PRD.md).\n\n## Problem Statement\n\nKylä's whole promise is that apps look coherent by default. But today the token\nsystem only ships semantic **color** tokens with _provisional_ hex values, plus\na single `--kyla-radius`. There is no spacing scale, no type scale, and no\ngraduated radius scale, and the palette has never been checked for AA contrast.\n\nThe consequence is already visible: the preview page hand-writes `px-4 py-2`,\n`text-lg`, `gap-6`, `mt-5`, `text-[10px]` — raw Twind numbers chosen ad hoc.\nEvery component built this way re-decides spacing and type independently, which\nis exactly the inconsistency Kylä exists to eliminate. Consumers who trust the\ndefault theme also have no guarantee that foreground/background pairings are\nlegible.\n\n## Solution\n\nShip a real, opinionated, **fixed** set of structural scales — spacing, radius,\nand type (size + line-height, with the font family and any needed weights) —\nplus a real, AA-verified color palette bound to the existing semantic tokens.\nBecause the structural scales are fixed and consumed by every component, spacing\nand type become consistent by construction. The consumer override surface stays\ndeliberately small (`--kyla-accent`, `--kyla-radius`, `--kyla-font`); everything\nstructural stays fixed — that fixedness _is_ the consistency (ADR-0001,\nCONTEXT.md).\n\nThe default palette carries AA contrast as a quiet guarantee (ADR-0003),\nverified mechanically rather than by eye.\n\n## User Stories\n\n1. As a consumer, I want a fixed spacing scale exposed as tokens, so that\n   padding and gaps are consistent across every component and every app without\n   me choosing pixel values.\n2. As a consumer, I want a fixed type scale (size + line-height), so that text\n   hierarchy is coherent without me hand-picking `text-*` classes.\n3. As a consumer, I want a font-family token I can override, so that I can\n   express brand while keeping the rest of the system fixed.\n4. As a consumer, I want a graduated radius scale derived from the overridable\n   `--kyla-radius`, so that rounding stays proportional when I change the base\n   radius.\n5. As a consumer, I want the default palette to meet WCAG AA contrast in both\n   light and dark mode, so that my app is legible without me auditing colors.\n6. As a consumer, I want the small override surface (accent, radius, font) to be\n   documented and stable, so that I know exactly what I may safely redefine.\n7. As a consumer, I want structural tokens (spacing, type, surfaces, borders) to\n   stay fixed, so that I cannot accidentally break visual consistency by\n   overriding them.\n8. As a component author, I want a sanctioned, typed way to reference scale\n   tokens, so that I compose spacing and type from the scale instead of raw\n   Twind numbers.\n9. As a component author, I want the scale accessors to sit alongside the\n   existing `tw` color helpers, so that authoring one component uses one\n   consistent vocabulary.\n10. As a component author, I want the type scale to bundle line-height with\n    size, so that I cannot set a size without its intended leading.\n11. As a maintainer, I want the palette's AA guarantee enforced by a test, so\n    that a future palette edit that breaks contrast fails CI rather than\n    shipping.\n12. As a maintainer, I want the scale definitions to live in one place\n    (`tokens.ts`), so that the design foundation has a single source of truth.\n13. As a maintainer, I want the scales expressed as CSS custom properties\n    resolved with `light-dark()` where mode-dependent, so that mode still flips\n    with zero JS.\n14. As an end user, I want legible text and comfortable spacing in whatever mode\n    my OS prefers, so that the app is usable by default.\n15. As a consumer upgrading, I want the scale token _names_ to be stable, so\n    that a Release that retunes values doesn't break my component usage.\n\n## Implementation Decisions\n\n- **Source of values (ADR-0005):** the palette and structural scales **conform\n  to the Val Town UI style guide** — they are _ported_, not invented here.\n  Concrete values come from the VT style-guide research/reference doc under\n  `docs/` (see\n  [ADR-0005](../../adr/0005-val-town-visual-language-default-theme.md)). This\n  PRD's job is to bind those values to the `--kyla-*` tokens and the scale\n  accessors, and to hold the AA line where a VT pairing falls short.\n- **Resolved default values** (from\n  [`val-town-style-guide.md`](../../reference/val-town-style-guide.md) §6; all\n  AA-passing both modes). Values are Tailwind v4 steps, applied via\n  `light-dark(light, dark)`:\n  - `base` = white / **`slate-950` `#020618`** (a deliberate softening of VT's\n    true-black `#000` — see ADR-0005); `elevated` = white+shadow / `slate-900`;\n    `recessed` = `slate-100` / `slate-800`.\n  - `fg` = black / white; `fg-muted` = `gray-600` / `gray-300` (VT's literal\n    `--color-muted`; **not** slate-400, which fails AA).\n  - `line` = `slate-200` / `slate-700`; `hairline` = `slate-100` / `slate-800`.\n  - `accent` = `sky-400` / `sky-700`; `accent-fg` = **`sky-950` ink** / white\n    (never white on `sky-400` — fails at 2.18:1); `accent-ring` = `sky-500`;\n    `accent-text` = `sky-800` / `sky-200`.\n  - `danger` = `rose-300` / `rose-800`; `danger-fg` = `rose-950` / white.\n    `success` = `emerald-400` / `emerald-700`; `success-fg` = `emerald-950` /\n    white.\n  - `radius` (base) = **8px** (`rounded-lg`); spacing base = 4px; font =\n    `\"IBM Plex Sans\",\n-apple-system, sans-serif` (needs shell/Provider font\n    loading — flag for delivery).\n- **New tokens (ADR-0005):** this PRD adds `accent-ring`, `accent-text`,\n  `danger-fg`, `success`, `success-fg` to the `ColorToken` union and the token\n  stylesheet, alongside the existing set. All are structural (not part of the\n  override surface).\n- **Modules touched:** `src/theme/tokens.ts` (add scale custom properties) and\n  `src/theme/tw.ts` (add typed scale accessors alongside the existing color\n  helpers). A new pure module for the AA-contrast check (used by tests) may be\n  added under `src/theme/`.\n- **Scale tokens to define** (names fixed by this PRD; exact numeric values are\n  the design deliverable _within_ this PRD):\n  - **Spacing:** a fixed stepped scale, `--kyla-space-*`. Monotonic, small step\n    count, built on a consistent base unit.\n  - **Type:** `--kyla-text-*` steps, each carrying a size **and** a line-height,\n    plus `--kyla-font` (overridable) and weight tokens if components need them.\n  - **Radius:** keep `--kyla-radius` as the single overridable base; derive a\n    small graduated set (`--kyla-radius-sm/md/lg`) from it.\n- **Override surface (formalized):** consumer-overridable = `--kyla-accent`,\n  `--kyla-radius`, `--kyla-font` (and their direct derivations). Everything else\n  — surfaces, foreground, borders, spacing scale, type scale — is structural and\n  stays fixed. Document this split in `tokens.ts` and CONTEXT.md's Override\n  Surface note.\n- **Accessor shape:** scale accessors follow the `tw.*` pattern. Lengths need no\n  `color:` hint (per the spike finding, only colors do), so spacing/radius/type\n  accessors emit bare arbitrary-value classes (e.g. `p-[var(--kyla-space-4)]`),\n  while a typo in the step is a compile error via a TypeScript union — mirroring\n  how `ColorToken` already guards color tokens.\n- **Palette:** replace every provisional hex with the resolved VT value above\n  for both modes, keeping the `light-dark()` structure. Every _sanctioned_\n  foreground/ surface pairing (`fg` on `base`/`elevated`/`recessed`, `accent-fg`\n  on `accent`, `danger-fg` on `danger`, `success-fg` on `success`, `fg-muted` on\n  surfaces used for secondary text) must meet WCAG AA: 4.5:1 for body text, 3:1\n  for large text and UI/border affordances.\n\n## Testing Decisions\n\n- **What makes a good test here:** it asserts an _external guarantee_ of the\n  foundation, not a specific hex or pixel. Two guarantees are worth testing:\n  contrast and scale integrity.\n- **Seam (highest available):** the token stylesheet string plus a **pure\n  contrast function** over resolved color values. This is the natural seam\n  because the guarantee (\"AA holds\") is a property of the values, computable\n  without a browser.\n  - Enumerate every sanctioned fg/surface pairing and assert its computed\n    contrast ratio meets the AA threshold in **both** modes. This is the load-\n    bearing test — it's what lets a future palette edit fail loudly.\n  - Assert the spacing and type scales exist, are monotonic, and expose the\n    documented step count.\n  - Assert the override tokens (`--kyla-accent`, `--kyla-radius`, `--kyla-font`)\n    are present and that structural tokens are present.\n- **Modules tested:** `tokens.ts` (via the parsed stylesheet) and the contrast\n  helper.\n- **Prior art:** none — this PRD establishes the repo's first test harness.

A developer who wants to build with Kylä has only the\nGallery (which shows components in isolation) and the README snippet (a single\nButton). There's no genuine, end-to-end example wiring together a real HTTP\nroute, persistence, the Provider + client hydration, an app shell, and a Mode\ntoggle — i.e. no honest demonstration that Kylä works as a whole for building an\nactual app.\n\n## Solution\n\nShip **`kyla-ui-starter`**: a small but genuine **todo app** that imports Kylä\nUI and is built entirely from its components. It has a real HTTP route,\n`std/sqlite` persistence, `KylaProvider` + client hydration, an app shell, a\nMode toggle, and a view-source link. Remixing it and editing is the intended way\nto start a new Kylä app. Building it also dogfoods the library and surfaces gaps\nin the component set.\n\n## User Stories\n\n1. As a new Kylä developer, I want a remixable Starter val, so that I can begin\n   a real app by copying a working example instead of assembling one.\n2. As a new developer, I want the Starter to be a genuine todo app (add / toggle\n   / delete, persisted), so that it demonstrates real behavior, not a static\n   mock.\n3. As a new developer, I want the Starter to persist todos with `std/sqlite`, so\n   that I see the idiomatic Val Town persistence pattern.\n4. As a new developer, I want the Starter to serve a real HTTP route, so that I\n   see how a Kylä app is served on Val Town.\n5. As a new developer, I want the Starter wrapped in `KylaProvider` with client\n   hydration, so that I see the correct Provider + CSR wiring (Twind before\n   first paint, tokens injected, Mode owned).\n6. As a new developer, I want the whole UI built from Kylä components, so that I\n   learn the components by seeing them composed in a real app.\n7. As a new developer, I want a Mode toggle in the Starter, so that I see how to\n   give an app a first-class light/dark toggle via `useKylaMode()`.\n8. As a new developer, I want a view-source link, so that I can jump from the\n   running app to its code.\n9. As a new developer, I want the Starter pinned to a known-good Kylä Release,\n   so that a fresh remix renders correctly and isn't broken by an in-flight\n   library change.\n10. As a maintainer, I want the Starter to depend on the library (never the\n    reverse), so that the dependency direction stays clean.\n11. As a maintainer, I want the Starter built from real components, so that it\n    doubles as an integration check that the set composes into an app.\n12. As an end user of the demo, I want to add, complete, and remove todos, so\n    that the app is actually usable.\n13. As an end user, I want my todos to persist across reloads, so that the demo\n    behaves like a real app.\n\n## Implementation Decisions\n\n- **Separate val:** `kyla-ui-starter` (per CONTEXT.md), distinct from `kyla-ui`.\n  It **imports** Kylä UI; the library never imports it.\n- **CSR-only** (sketch/ADR-0001): an HTML shell loads Twind before first paint,\n  a client entry hydrates the app, and `KylaProvider` wraps it (owning tokens +\n  Mode). Same shell mechanics the Gallery/preview use (importmap for `npm:`\n  specifiers, `std/catch`, `serveFile`).\n- **Persistence:** `std/sqlite` (project-scoped DB) for the todo list.\n- **HTTP route:** serves the shell and handles todo mutations — list, add,\n  toggle complete, delete — round-tripping through sqlite.\n- **UI built from Kylä components:** app shell, `Card`, `Input`, `Button`,\n  `Text`/`Heading`, `Stack`, etc., plus the Mode toggle via `useKylaMode()`.\n  Using `Dialog` (e.g. a confirm-delete) is encouraged once it ships, to\n  demonstrate the own-import-path pattern.\n- **Version pinning (decided here):** the Starter **pins** its Kylä import to a\n  known-good `?v=NNN` Release, so a remix is a stable starting point rather than\n  tracking `main` mid-change (ADR-0004). Document which Release it targets; bump\n  deliberately.\n- **view-source link** to the Starter val, matching the preview/Gallery pattern.\n\n## Testing Decisions\n\n- **What makes a good test:** it drives the app's _external_ HTTP behavior — the\n  todo operations round-tripping through sqlite — not the internal React tree or\n  the library's internals (those are the component PRDs' concern).\n- **Seam (HTTP, highest available for the app):** exercise the route endpoints\n  and assert the todo lifecycle: adding a todo returns/lists it, toggling flips\n  its completed state, deleting removes it, and the list reflects persisted\n  state on a fresh request. Optionally assert the served shell is a `200` HTML\n  page that boots the client entry.\n- **Modules tested:** the Starter's HTTP handler + its sqlite data access.\n- **Prior art:** Val Town `std/sqlite` HTTP-handler patterns (fetch a template\n  via the platform's skill finder); the `preview/index.tsx` handler is the\n  reference for the serve-shell-and-files structure on Val Town.\n\n## Out of Scope\n\n- Auth / multi-user / per-user todo lists.\n- Isomorphic SSR + hydration for SEO (sketch defers this; CSR-only for v1).\n- Demonstrations beyond the todo app (other example apps).\n- The **Gallery** / component docs — those live in the library\n  ([Gallery PRD](../gallery/PRD.md)), not the Starter.\n\n## Further Notes\n\n- The Starter is the honest integration test of the whole v1: if composing it\n  into a real app is awkward, that's a signal to fix the component set, not to\n  work around it in the Starter.\n- Keep it \"tiny but genuine\" — enough to be a real app, small enough to read in\n  one sitting, since developers will copy it as their baseline.\n",[],[212,462,569,33],"starter","7e7e92e4-11ce-4ac1-8024-cd86ab3686e3","03-todo-ui-and-mode-toggle.md","7db91958-7b2a-11f1-ac5e-1607ee4eb77e","7d76a5a0-7b2a-11f1-92f9-1607ee4eb77e",197,["D",1784058611348],"# 03 · Todo UI + Mode toggle\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n## Parent\n\n[PRD: Starter — remixable todo app](../PRD.md)\n\n## What to build\n\nWire the todo UI — built entirely from Kylä components — to the CRUD route, and\ngive the app a first-class light/dark toggle via the library's own Mode\nownership.

There is no blessed docs surface a consumer\ncan point to.\n\n## Solution\n\nPromote `preview/` into the real **Gallery** served at `kyla-ui`'s HTTP route:\nit renders every shipped component across its variants/sizes/tones, shows the\ndesign token swatches, and carries the Mode toggle driven by the library's own\n`useKylaMode()`. It imports the real library and never modifies it. It is the\ncanonical proof-of-render on Val Town and the seed of a fuller docs site later.\n\n## User Stories\n\n1. As a consumer evaluating Kylä, I want a live Gallery at the library's URL, so\n   that I can see every component before importing it.\n2. As a consumer, I want each component shown in all its variants/sizes/tones,\n   so that I can pick the right props by seeing them.\n3. As a consumer, I want a Mode toggle (light/dark/system) in the Gallery, so\n   that I can verify how components look in each Mode.\n4. As a consumer, I want the token swatches shown, so that I can see the\n   semantic palette the system is built on.\n5. As a consumer, I want a view-source link, so that I can read how the Gallery\n   uses the components.\n6. As a maintainer, I want the Gallery served from `kyla-ui` itself (co-located\n   with source), so that the library documents itself and the docs can never\n   drift from the code they import.\n7. As a maintainer, I want the Gallery to import the real library and never\n   modify it, so that it's an honest proof-of-render, not a mock.\n8. As a maintainer, I want the Gallery to be the in-browser proof that Twind +\n   tokens + Provider + Radix render correctly on Val Town, so that a broken\n   render path is visible immediately.\n9. As a maintainer, I want adding a new component to the Gallery to be a small,\n   obvious edit, so that the docs stay current as the set grows.\n10. As a contributor, I want the Gallery to exercise the interactive components\n    (focus rings, Dialog open/close), so that it doubles as a manual behavior\n    check.\n11. As an end user of the docs, I want the Gallery to load without a build step,\n    so that it works on Val Town's runtime like any consumer app.\n\n## Implementation Decisions\n\n- **Home:** served from `kyla-ui`'s HTTP route (the val documents itself). Reuse\n  the shell _mechanics_ from `preview/`: Twind loaded before first paint\n  (ADR-0001), the importmap that maps `npm:` specifiers to esm.sh for the\n  browser, `std/catch` for client-error surfacing, `serveFile` for transpiled\n  `.ts/.tsx`, and the `/source` redirect. The Gallery **imports** the library\n  from `mod.ts` (and Dialog's own path) and modifies nothing — the preview's\n  core invariant.\n- **Shell conventions (folded-in cleanup — see issue\n  [`01-preview-shell-conventions`](issues/01-preview-shell-conventions.md)):**\n  the Gallery adopts the _corrected_ shell, not today's template-literal one — a\n  real `index.html` static file served via `serveFile`, and no inline `<style>`\n  block (Twind utility classes only, per project convention). This cleanup is\n  small and can land early against `preview/` before the full Gallery is built;\n  the Gallery then inherits it.\n- **Content:** one section per shipped component showing its full variant/size/\n  tone matrix, plus the token swatches and the interactive examples. The Mode\n  toggle is driven by `useKylaMode()` (not a hand-rolled toggle) — dogfooding\n  the Provider's Mode ownership.\n- **Generation approach (open question in the sketch — decided here):**\n  **hand-written** sections per component for v1. A metadata-driven generator\n  (the sketch's alternative) is deferred until the component set stabilizes;\n  hand- written is lower-risk and needs no new metadata layer.\n- **Relationship to `preview/`:** this supersedes `preview/` as the canonical\n  surface. The WIP banner and \"not a stable API\" framing are dropped once it's\n  the blessed Gallery; the corrected shell (above) is kept.\n- **Dialog:** once [Dialog](../dialog-radix/PRD.md) ships, the Gallery is where\n  its open/close/focus-trap behavior is manually verifiable in-browser (the\n  behavior backstop that PRD refers to).\n\n## Testing Decisions\n\n- **What makes a good test:** it asserts the Gallery's _external_ HTTP behavior\n  — that the route serves, and that the served markup contains the expected\n  proof — not the internal React tree.\n- **Seam (HTTP, highest available for a served surface):** fetch the Gallery\n  route and assert:\n  - a `200` with an HTML content-type;\n  - each shipped component's section is present;\n  - token utility classes (e.g. `bg-[color:var(--kyla-…)]`) appear in the served\n    markup — a direct check that the render path emits the hinted classes rather\n    than silently dropping them.\n- **Behavior (browser, optional backstop):** the Mode toggle flipping the\n  palette and Dialog interactions are the higher-fidelity checks; run them in a\n  real browser against the live Gallery. Not required for the PRD's automated\n  seam.\n- **Modules tested:** the Gallery's HTTP handler.\n- **Prior art:** the existing `preview/index.tsx` handler (shell + `serveFile` +\n  `/source`) is the working reference for serving on Val Town.\n\n## Out of Scope\n\n- **Metadata-driven Gallery generation** (deferred; hand-written for v1).\n- A fuller prose/MDX docs site (the Gallery is its seed, not its replacement).\n- The **Starter** val — [separate PRD](../starter/PRD.md).\n- Building the components themselves —\n  [component set PRD](../v1-component-set/PRD.md).\n\n## Further Notes\n\n- The Gallery is load-bearing beyond docs: because the Twind \"missing `color:`\n  hint\" failure is _invisible_, the Gallery is the fastest place a human spots\n  an unstyled element. Keep it exercising real components in real Modes.\n",[],[212,462,613,33],"gallery","5317b761-04d8-4c89-81cb-51e30a9b5af7","03-gallery-dialog-backstop.md","7dc6339a-7b2a-11f1-914c-1607ee4eb77e","45a5c9e0-798a-11f1-80ac-1607ee4eb77e",187,["D",1784058610397],"# 03 · Wire Dialog into the Gallery as the behavior backstop\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n## Parent\n\n[PRD: Gallery — self-hosted docs surface](../PRD.md)\n\n## What to build\n\nAdd `Dialog` to the Gallery so its interactive behavior is manually verifiable\nin-browser — the behavior backstop the [Dialog PRD](../../dialog-radix/PRD.md)\nrefers to (open/close, focus-trap, ESC, in-portal token resolution), which the\nrender-seam test deliberately does not cover.\n\nEnd-to-end behavior:\n\n- A Gallery section that imports `Dialog` from its own path (not the barrel) and\n  renders a real, openable example exercising trigger/content/title/description/\n  close.\n- The example confirms, in a real browser against the live Gallery, that the\n  dialog opens/closes, traps focus, closes on ESC and overlay click, and that\n  token custom properties resolve correctly through the Radix portal in both\n  Modes.\n\n## Acceptance criteria\n\n- [ ] The Gallery renders an openable `Dialog` example imported from Dialog's\n      own path (Dialog stays out of the `mod.ts` barrel).\n- [ ] Open/close, focus-trap, ESC, and overlay-click close are manually\n      verifiable in-browser against the live Gallery.\n- [ ] In-portal token resolution is correct in both light and dark Mode (no\n      wrong-theme flash inside the modal).\n\n## Blocked by\n\n- [02 — Promote preview into the canonical Gallery](./02-gallery-build.md)\n- [dialog-radix 01 — Dialog behind its own import path](../../dialog-radix/issues/01-dialog-radix-component.md)\n",[],[212,462,613,462,615],"9883e3bd-e74e-4cda-910c-d8b2cf6a9920","02-gallery-build.md","7d9f80c4-7b2a-11f1-ac5e-1607ee4eb77e",186,["D",1784058610297],"# 02 · Promote preview into the canonical Gallery\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n## Parent\n\n[PRD: Gallery — self-hosted docs surface](../PRD.md)\n\n## What to build\n\nPromote the WIP `preview/` into the real **Gallery** served at `kyla-ui`'s HTTP\nroute: the blessed, self-hosted docs surface that renders every shipped\ncomponent in its variants and Modes, and the in-browser proof that Twind +\ntokens + Provider render correctly on Val Town.\n\nEnd-to-end behavior:\n\n- Served from `kyla-ui`'s HTTP route, reusing the _corrected_ shell mechanics\n  (Twind before first paint, importmap for `npm:` specifiers, `std/catch`,\n  `serveFile`, `/source` redirect).

The Gallery adopts the\ncorrected shell this issue produces, so this can land early against `preview/`\nbefore the full Gallery is built. Target: `nbbaier/kyla-ui`, file\n`preview/index.tsx`.\n\n## Context\n\n`preview/`'s route was reviewed against Val Town's documented React/HTTP\nconventions. Two deviations in the HTML shell built inside `preview/index.tsx`:\n\n1. **HTML shell is a template-literal string, not a real file.** The full\n   `<!doctype html>` document is built as a JS template literal and returned via\n   `new Response(html, ...)`. Val Town's own `templates/react-hono-starter`\n   ships a real `frontend/index.html` static file served via `serveFile()`,\n   satisfying the same \"Twind must load before first paint\" requirement\n   (ADR-0001) with a `<script>` tag in that static file. Template-literal HTML\n   gets no syntax highlighting, linting, or type checking.\n2. **Inline `<style>` block in the shell.** The template literal includes a\n   `<style>` tag (body margin reset + the `#root:empty::before` \"Loading\n   preview…\" placeholder). Project convention is Twind/Tailwind utility classes\n   only — no inline `<style>` tags or hand-written CSS.\n\n## Proposed fix\n\n- Extract the shell markup into a real `preview/index.html` file, keeping the\n  Twind `<script>` tag, the importmap (for the `npm:clsx` / `npm:tailwind-merge`\n  specifiers), and the `std/catch` error-reporting script exactly as they are\n  today.\n- Update `preview/index.tsx` to serve that file via\n  `serveFile(\"/preview/index.html\", import.meta.url)` instead of the inline\n  template string. Keep the existing `/source` redirect and the `.ts/.tsx`\n  passthrough (for `client.tsx`, `app.tsx`, `../mod.ts`, etc.) unchanged.\n- Replace the inline `<style>` block with Twind utility classes. The\n  `#root:empty::before` loading-placeholder trick has no direct Tailwind\n  equivalent for `:empty` — either keep one minimal, clearly-commented `<style>`\n  rule just for that, or (preferred, if simple) render an explicit loading\n  placeholder element inside `#root` in the HTML so Twind classes style it\n  directly and the `<style>` tag can be dropped entirely.\n\n## Acceptance criteria\n\n- `preview/index.tsx` no longer contains a template-literal HTML string.\n- No inline `<style>` tag remains, or the one narrow exception is commented with\n  why Twind can't express it.\n- Twind script, `catch` script, importmap, and `/source` redirect all still\n  present and working.\n- `preview/` route verified via `fetch_val_endpoint` after the change — the page\n  still renders the Button / token / mode-switcher showcase with no console\n  errors (check `get_logs`).\n\n## Out of scope\n\n- Kylä UI's Button variant names (`primary`/`subtle`/`ghost`/`danger`) and size\n  scale (`sm`/`md`/`lg`) intentionally differ from `val.town/_ui`'s own\n  vocabulary — a deliberate design choice (modeled on Cloudflare Kumo per\n  CONTEXT.md), not a bug to fix.\n",[],[212,462,613,462,632],"92a7eda9-25fb-4409-9008-b01d2d410386",85,["D",1783377020590],[247,248,249],[212,462,613,462],"217cca91-a478-4fc0-b891-d1f7c65035ee",81,["D",1783377020017],[246,250],[212,462,613],"d106619c-aee5-4376-9d1e-185ab1b4864c","45ccb3ca-798a-11f1-8ef5-1607ee4eb77e","453bae52-798a-11f1-97fb-1607ee4eb77e",219,["D",1784059569437],"# PRD: Dialog (Radix-backed)\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n> Brings the first Radix-backed component into the library, exercising the\n> hybrid-headless split (ADR-0002) and the version-pinned distribution contract\n> (ADR-0004) in real code — not just the throwaway spike. Depends on the\n> [v1 component set](../v1-component-set/spec.md) for surrounding styled pieces\n> and on the [scales & palette](../structural-scales-palette/spec.md) for tokens.\n\n## Problem Statement\n\nKylä's architecture bets on a **hybrid foundation**: hand-roll simple visual\ncomponents with zero dependencies, and build the hard interactive ones on a\nheadless library (ADR-0002). That bet is currently proven only in a separate\nthrowaway val (`nbbaier/kyla-ui-spike`). No hard interactive component ships in\nthe library, so the load-bearing mechanics — Radix imported behind its own\nimport path, kept out of the barrel so it only loads when used, with the\nReact-18.2.0 `?deps=` pin propagated through Radix's transitive graph — are\nunexercised in the real codebase.\n\n## Solution\n\nBring **`Dialog`** into the library as the first Radix-backed component. It\nlives behind its own import path (a root re-export, e.g. `dialog.tsx`) kept\n**out** of the `mod.ts` barrel, so consumers who never use it never load Radix.\nIt is styled entirely from the token system like every other component; its\nbehavior and accessibility (focus trap, ESC, `aria-*`, portal) are delegated to\nRadix. The public surface stays styling-only — Radix primitives remain internal\nso a later Radix→Base UI swap isn't an API break.\n\n## User Stories\n\n1. As a consumer, I want a `Dialog` component styled on-system, so that modals\n   match the rest of my Kylä app.\n2. As a consumer, I want to import `Dialog` from its own path, so that apps that\n   don't use it never pay Radix's download/parse cost.\n3. As a consumer, I want the `Dialog` to trap focus and close on ESC and overlay\n   click, so that it's accessible without me wiring ARIA by hand.\n4. As a consumer, I want `Dialog` to compose the way I'd expect (trigger,\n   content, title, description, close), so that I can build real modals.\n5. As a consumer, I want the token theme (surfaces, accent, radius) to apply\n   inside the modal, including through the portal, so that light/dark mode is\n   correct everywhere.\n6. As a consumer, I want to override the content's `className`, so that I can\n   size or position a specific dialog without forking.\n7. As a consumer pinning a version, I want `Dialog` to work under the pinned\n   React 18.2.0, so that Radix's transitive deps don't hit the `useState` null\n   mismatch.\n8. As a component author, I want Radix primitives kept internal to the Dialog\n   module, so that swapping to Base UI later doesn't change the public API.\n9. As a maintainer, I want `Dialog` excluded from the `mod.ts` barrel, so that\n   the zero-dep core stays zero-dep.\n10. As a maintainer, I want the React-version pin applied at Radix's import, so\n    that the spike's mismatch finding is encoded in shipping code.\n11. As an end user, I want a modal that manages focus and keyboard correctly, so\n    that I can use it with assistive tech.\n12. As an end user, I want the dialog's colors to match my OS light/dark\n    preference, so that it doesn't flash the wrong theme.\n\n## Implementation Decisions\n\n- **Modules built:** `src/components/dialog.tsx` (styled composition over Radix)\n  plus a root re-export path (e.g. `dialog.tsx` at the repo root) that is the\n  consumer's import URL. **Not** added to `mod.ts` (ADR-0002/0004).\n- **React pin (spike finding, load-bearing):** import Radix with\n  `?deps=react@18.2.0,react-dom@18.2.0` so the pin propagates through Radix's\n  whole transitive graph and defuses the React-mismatch `useState` null error.\n- **Public API is styling-only:** expose a composed, token-styled Dialog surface\n  (root/trigger/content/overlay/title/description/close). Radix's own primitives\n  are an internal implementation detail and are not re-exported, so a later\n  Radix→Base UI variant is not an API break.\n- **Tokens through the portal:** content uses the `elevated` surface, overlay a\n  scrim, focus ring from tokens; verify token custom properties resolve inside\n  the Radix portal (the spike confirmed `light-dark()` resolves in-portal).\n- **Radix first** (proven on VT); a Base-UI-backed variant stays deferred.\n- **Twind hint discipline still applies** inside the portal — all colors go\n  through the `tw` helpers (ADR-0001), no bare `[var(--…)]` color utilities.\n\n## Testing Decisions\n\n- **What makes a good test:** it verifies **our** contribution — that we mounted\n  Radix with the right props and token styling — and does **not** re-test\n  Radix's own guarantees. Testing that Radix traps focus is testing Radix, not\n  Kylä.\n- **Two-level seam:**\n  - **Primary (server-render, uniform with the component set):** render the\n    Dialog's trigger/closed surface (and the content in an open-by-default\n    configuration where feasible) to an HTML string and assert our wiring —\n    token utility classes present on overlay/content, `className` override wins,\n    title/ description associated, close affordance present. This catches the\n    silent Twind hint failure the same way as the rest of the set.\n  - **Behavior backstop (browser):** open/close, focus-trap, ESC, and in-portal\n    token resolution are interaction guarantees best confirmed in a real browser\n    — via the [Gallery](../gallery/spec.md) once Dialog is listed there. Treat\n    this as the higher-fidelity seam for _behavior_, not a unit test of Radix\n    internals.\n- **Modules tested:** `src/components/dialog.tsx` (render seam).\n- **Prior art:** the render-to-HTML harness from the\n  [v1 component set](../v1-component-set/spec.md); the spike val is the reference\n  for the working Radix + React-pin + portal configuration.\n\n## Out of Scope\n\n- Other Radix-backed components (`Popover`, `Menu`, `Tabs`, `Tooltip`,\n  `Combobox`, `Toast`) — v1.1+.\n- The **Base UI** variant (deferred until Radix proves the path).\n- Adding `Dialog` to the barrel (deliberately excluded).\n\n## Further Notes\n\n- This PRD is the real-code payoff of the spike. If anything in the spike's\n  Radix configuration proves brittle in the library, capture it as an ADR update\n  rather than a local workaround.\n- Because `Dialog` defines the _pattern_ for every future Radix-backed\n  component, keep the internal/exposed boundary crisp — it's what protects the\n  Radix→Base UI option.\n",[],[212,462,657,37],"dialog-radix","eea6b906-d215-4c4c-a307-f60e98a0f5e5","01-dialog-radix-component.md","7d915dc8-7b2a-11f1-801b-1607ee4eb77e","7d421ede-7b2a-11f1-914c-1607ee4eb77e",183,["D",1784058610088],"# 01 · Dialog behind its own import path (Radix + React pin + token styling)\n\nStatus: ready-for-agent Labels: ready-for-agent\n\n## Parent\n\n[PRD: Dialog (Radix-backed)](../PRD.md)\n\n## What to build\n\nBring `Dialog` into the library as the first Radix-backed component, encoding\nthe hybrid-headless split (ADR-0002) and the version-pinned distribution\ncontract (ADR-0004) in shipping code.

This doc is a pointer map + \"what's\nnext\", not a re-spec — the real content lives in the artifacts referenced below.\n\n## Read these first (don't duplicate them)\n\n- [`CONTEXT.md`](../../CONTEXT.md) — glossary / shared language.\n- [`docs/v1-design-sketch.md`](../v1-design-sketch.md) — the design hub,\n  **Implementation status** section, open spikes (all ✅), and the \"Deliberately\n  deferred\" list.\n- [`docs/adr/0001..0004`](../adr/) — the load-bearing decisions and _why_.\n- [`README.md`](../../README.md) — consumer-facing quick start.\n\n## State of the world\n\n- **Two vals.** `nbbaier/kyla-ui` (the library; locally synced to this working\n  dir via `vt`). `nbbaier/kyla-ui-spike` (throwaway substrate proof — all 4\n  spikes green in-browser; keep it around as a live sandbox).\n- **Foundation built & verified on the runtime:** `mod.ts` barrel + `src/utils/`\n  (`cn`, `variants`), `src/theme/` (`tokens`, `tw`, `provider`),\n  `src/components/` (`button`). Layout rationale is in the sketch's\n  Implementation status.\n- **`Button`** ships with `variant` × `size`, token focus ring, ref forwarding,\n  escape-hatch `className`. Verified by server-render (`renderToStaticMarkup`).\n- Everything is pushed; `vt status` was clean at handoff time.\n\n## Gotchas that will bite you if forgotten\n\n1. **The `color:` hint is mandatory** for token color utilities —\n   `bg-[color:var(--…)]`, never `bg-[var(--…)]` (the latter silently renders\n   nothing; no error). Always go through the `tw.*` builders in\n   `src/theme/tw.ts`, which bake it in. (ADR-0001.)\n2. **Twind lives in the HTML shell**, not the Provider (must load before first\n   paint). The Provider injects only the token stylesheet. (ADR-0001.)\n3. **Pin React to 18.2.0 everywhere**, including Radix via\n   `?deps=react@18.2.0,react-dom@18.2.0`, or you hit the `useState` null error.\n   (ADR-0002.)\n4. **`cn(componentClasses, className)` call order** is the contract — caller's\n   `className` must come last to win.\n5. **Token values in `src/theme/tokens.ts` are provisional** — not the real\n   palette yet.\n\n## Suggested next steps (roughly in order)\n\n1. **See `Button` live** — add a showcase row to `kyla-ui-spike`'s `App.tsx` to\n   eyeball all variant/size combos + hover/focus in a browser. (Quick\n   loop-closer.)\n2. **Real palette + structural scales** — replace provisional tokens with\n   AA-checked surface/fg/border ramps + spacing/radius/type scales.\n   Highest-leverage deferred item.\n3. **More components** — `Card`, `Text`/`Heading`, `Input`, `Textarea`, `Label`,\n   `Badge`, `Stack`, `Box`, `Divider`, then native-styled `Select`. Reuse the\n   Button pattern.\n4. **`Dialog` (Radix)** — first component behind its own import path:\n   `src/components/dialog.tsx`\n   - a root `dialog.ts` re-export, kept OUT of `mod.ts` (ADR-0002). Exercises\n     the split.\n5. **Gallery** — the library's self-hosted docs HTTP route (CONTEXT.md →\n   \"Gallery\").\n6. **Starter** — `kyla-ui-starter`: a tiny todo app (CONTEXT.md → \"Starter\").\n\n## How to work in this repo\n\n- Edit locally, then `vt push` (and `vt pull` first if needed). `vt status`\n  shows drift.\n- **Smoke-test pattern that works without a browser:** create a throwaway\n  `src/_smoke.ts(x)` in the val, `run_file` it (use `renderToStaticMarkup` from\n  `react-dom@18.2.0/server` to render components to a class string), then\n  `delete_file` it. Used twice this thread; clean and fast.\n- For anything UI/platform-specific on Val Town, pull the official skill via the\n  valtown MCP `find_val_town_skills` tool rather than working from memory.\n\n## Suggested skills for the next session\n\n- **valtown:react-ui** — the canonical conventions (Twind, React pin,\n  view-source) for any component or Gallery work.\n- **grill-with-docs** — if revisiting design decisions (palette, theming v2, new\n  components' APIs); it updates `CONTEXT.md` / ADRs inline.\n- **valtown:sqlite-storage** + **valtown:http-endpoints** — when building the\n  Starter todo app and/or the Gallery route.\n- **rams** (or **impeccable**) — accessibility / visual-design review once there\n  are enough components and the real palette to evaluate.\n",[],[212,691,683],"handoffs","a7030e21-e7a7-4098-b3a8-8ab22885d8dc",59,["D",1781814739944],[239],[212,691],"2f0b95ab-6e0e-43f8-ba59-02b6dfc199b7","triage-labels.md","a548ab54-775c-11f1-8e89-1607ee4eb77e","a519c118-775c-11f1-8e89-1607ee4eb77e",180,["D",1784058609807],"# Triage Labels\n\nThe skills speak in terms of five canonical triage roles.

We decide that the default theme's\n**values** — color palette (light + dark), the spacing / radius / type scales,\nand the component-level styling those map to — **conform to the Val Town UI\nstyle guide** (`val.town/_ui`), so that an app built with Kylä looks native to\nVal Town rather than like a foreign design system dropped onto the platform.\n\nThis is a decision about **values, not architecture and not API**. It changes\nwhat the `--kyla-*` tokens resolve to; it does not change how the system is\nbuilt or how consumers call it:\n\n- **Architecture stays Kumo-modeled.** Semantic tokens as CSS custom properties\n  (ADR-0001), the hybrid headless foundation (ADR-0002), primitives + components\n  — all unchanged. The token indirection is precisely what lets us retarget the\n  look without touching components.\n- **API vocabulary stays Kylä's own.** Kylä keeps its Kumo-style variant model —\n  `Button` `variant` = `primary | subtle | ghost | danger`, `size` =\n  `sm | md | lg`, etc. — which deliberately differs from `val.town/_ui`'s own\n  class vocabulary. Adopting VT's _values_ does not rename Kylä's _props_. (This\n  is consistent with the note in the Gallery's preview-shell issue: the\n  divergence recorded there was about **names**, not **palette**.)\n- **Positioning (ADR-0003) is reinforced, not changed.** \"Lead with consistency\"\n  now means consistency _with the surrounding Val Town platform_, not just\n  internal self-consistency.\n\n## Source of truth for the values\n\nThe values are extracted from Val Town's own style guide and captured in\n`docs/reference/val-town-style-guide.md`, so downstream PRDs consume concrete\nnumbers rather than \"conform to VT\" prose. Primary sources (Val Town's site is\nRemix, server-rendered, so the component markup and its compiled token CSS are\nfetchable over plain HTTPS):\n\n- `https://www.val.town/_ui/*` — the live style-guide pages (button, callout,\n  card, dropdown, input, select, textarea, forms, privacy-badge); SSR markup\n  gives each component's verbatim utility classes.\n- `https://static2.esm.town/assets/tailwind-*.css` — the compiled Tailwind v4\n  stylesheet the pages link: the `@theme` token scale (`--color-*` oklch ramp,\n  `--spacing`, `--radius-*`, `--text-*`, fonts, weights) and VT's semantic\n  aliases split across `:root`/`.dark`.\n- `https://www.val.town/x/dcm31/townie-mobile/code/frontend/style.css` — a\n  hand-distilled token artifact billed by its author as Val Town's style guide\n  (\"gave Fable our style guide\"); used as a corroborating cross-check (it is\n  Tailwind v3, so the live `_ui` v4 values are treated as source of truth).\n\n## Considered Options\n\n- **Invent an opinionated palette/scale (Kumo-flavored)** — rejected: arbitrary,\n  and it forfeits the chance to make Kylä apps look like they belong on their\n  host platform. A bespoke look is a liability, not a feature, for this\n  audience.\n- **Adopt VT's values _and_ its class vocabulary** — rejected/deferred:\n  API-breaking, and Kylä's typed variant model is more expressive than raw\n  utility classes. Revisit only if there's a concrete reason to mirror VT's prop\n  names; it is explicitly **not** part of this decision.\n- **Adopt VT's values as the default theme; keep Kylä's architecture and API** —\n  **chosen.**\n\n## Consequences\n\n- The `structural-scales-palette` PRD is reframed: instead of _designing_ a\n  palette + scales, it **ports** the Val Town style guide's palette and scales\n  into the token stylesheet, sourced from the reference doc above. This is why\n  the decision must be recorded before that PRD is implemented.\n- **Coverage parity is the bar, not just palette adoption.** The\n  `v1-component-set` PRD uses `val.town/_ui` as the styling reference for its\n  per-component variant→token maps (button sizing/radius, input styling, badge\n  tones) — but \"conforms to VT\" means matching the _set_ of variants, states,\n  and techniques VT ships per component (color variants, icon-only sizing,\n  hover/active/disabled states, mode-adaptive techniques like `blend`'s\n  `mix-blend-mode`), not only porting palette hex/oklch values onto whatever\n  variant list a component already happens to have. Kylä's prop _names_ stay its\n  own (previous bullet); the _coverage_ those names collectively provide must\n  match VT's per-component surface, checked against\n  `docs/reference/val-town-style-guide.md`. This applies retroactively: a\n  component the roadmap already marks \"Built\" (e.g. `Button`, shipped with 4 of\n  VT's 7 button variants) is still subject to this bar and gets a revision\n  slice, not a pass.\n- **AA contrast (ADR-0003) remains the stricter constraint.** Every sanctioned\n  foreground/surface pairing must meet WCAG AA in both modes. If VT's guide has\n  a pairing that falls short, Kylä's AA guarantee wins and that token value is\n  adjusted; the contrast test enforces this regardless of source.\n- **Kylä keeps its own surface hierarchy.** The extraction\n  (`docs/reference/val-town-style-guide.md`) found VT's _semantic_ layer is\n  thinner than Kylä's — VT names only\n  `background / text / border / muted / shadow` and elevates by shadow over a\n  single surface. Kylä retains its structural `base` → `elevated` → `recessed`\n  hierarchy and `hairline` (CONTEXT.md); where VT has no named token, those\n  values are sourced from VT's slate component fills. So the default theme is\n  **VT's palette under Kylä's structure**, not a strict subset of VT's tokens.\n- **The token vocabulary expands to cover VT's accent + status roles.** VT uses\n  accent in three roles a single `accent`/`accent-fg` can't hold (fill,\n  focus-ring, accent-text-on-surface), and ships a success tone. The canonical\n  `--kyla-*` vocabulary therefore gains `accent-ring`, `accent-text`,\n  `danger-fg`, and a `success`/`success-fg` tone (updating CONTEXT.md's token\n  list and the `ColorToken` union). These are **structural** additions — the\n  consumer override surface stays small.\n- **One deliberate deviation from VT:** the dark-mode `base` uses `slate-950`\n  (`#020618`), a considered softening of VT's literal true-black (`#000`, 21:1)\n  to reduce large-surface glare. Recorded here so it reads as a choice, not an\n  extraction error; every other default tracks VT.\n- The consumer **override surface** (`--kyla-accent`, `--kyla-radius`, font) is\n  unchanged; its _defaults_ become the VT values, and a consumer can still\n  rebrand within that small surface.\n- If Val Town revises its style guide, Kylä tracks it by re-running the\n  extraction and retuning token values — a values change under the existing\n  Release contract (ADR-0004), not an API change.\n",[],[212,737,729],"adr","24aa19a0-a22a-44e0-a21e-34167b7ce4ed","0004-version-pinned-upgrade-contract.md","bcb00034-6b46-11f1-9b3f-1607ee4eb77e",217,["D",1784058614083],"# Upgrade contract: main-as-release-line, version pinning\n\nKylä UI is consumed by importing its val from esm.town, where an unpinned import\n(`.../kyla-ui/mod.ts`) auto-redirects to the val's latest version and a consumer\ncan freeze onto a specific version with `?v=NNN`. esm.town does **not** offer\nbranch-name import URLs, so the intuitive \"consumers track a long-lived `stable`\nbranch\" model is not available.\n\nWe therefore make **`main` the stable/release line**: all development happens on\nfeature/dev branches, and a **Release is a merge into `main`.** Because raw work\nnever lands on `main`, HEAD-of-`main` is always a Release.

On\nVal Town a headless library is an unvetted heavy ESM dependency loaded from a\nCDN at runtime, so we take it selectively: **simple visual components (Button,\nCard, Stack, Text, Input, Badge) are hand-rolled with zero dependencies**, and\n**only the genuinely hard interactive components (Dialog, Popover, Menu, Tabs)\nbuild on a third-party headless library.** This keeps the common case\ndependency-free and fast on Val Town while still inheriting accessibility where\nit is expensive to get right.\n\nThe library is **Radix first** — chosen over the maintainer's preferred Base UI\npurely because Radix has a longer track record loading from CDNs — used to prove\nthe pattern works on Val Town. A Base-UI-backed variant is a likely later step\nonce viability is demonstrated.\n\n## Consequences\n\n- Open validation task before committing: confirm a Radix primitive (e.g.\n  Dialog) imports via esm.sh with React pinned to 18.2.0 and hydrates cleanly on\n  Val Town's CSR setup.\n- Swapping the headless library later is contained per-component, not a global\n  rewrite — which is what makes \"Radix now, Base UI later\" affordable.\n",[],[212,737,755],"64148f51-d4d1-4308-b92b-872e98462b3a","0001-no-build-styling-architecture.md","bcbd4aa0-6b46-11f1-9db1-1607ee4eb77e",175,["D",1784058609426],"# No-build styling architecture\n\nKylä UI targets Val Town, which has no build step or bundler. Cloudflare Kumo —\nour model — achieves visual consistency with Tailwind v4 semantic tokens\ncompiled at build time, which we cannot use. We therefore deliver consistency at\nruntime: **semantic design values are defined as CSS custom properties** (a\ntoken stylesheet served by the `kyla-ui` val, using `light-dark()` for automatic\ndark mode), and **components apply them via runtime Twind arbitrary-value\nutilities** (e.g. `bg-[var(--kyla-base)]`). Styles are delivered with a\ndeliberate split (confirmed by the `kyla-ui-spike`): the **Twind script lives in\nthe HTML shell** (it must load before first paint or utilities FOUC, so it\ncannot be React-injected), while the **token stylesheet is injected by the\nProvider at runtime** (idempotently). The Starter ships the shell tag; the\nProvider guarantees the tokens — so \"styles are present\" is a guarantee, not a\nsetup checklist (a manual two-tag `<head>` setup is the documented escape\nhatch).\n\n## Considered Options\n\n- **Tailwind v4 + build step (the Kumo way)** — rejected: requires a\n  bundler/PostCSS, which Val Town does not provide.\n- **Twind with a named-token theme config** (`bg-kyla-base`) — rejected: every\n  consumer app would have to load an identical Twind runtime config or\n  components render wrong; that coupling is a sharp, silent failure mode.\n- **Pure CSS component classes** (`.kyla-button`) — rejected: self-contained but\n  abandons Tailwind/Twind ergonomics and composable variants, and strays from\n  the Val Town idiom.\n\n## Consequences\n\n- Arbitrary-value Twind syntax is noisier, but it lives inside library source;\n  consumers only write `<Button>`.\n- Components only render correctly where Twind is running and the token\n  stylesheet is loaded — hence the Provider (see ADR-0002's sibling delivery\n  decision) is load-bearing.\n- The `light-dark()` CSS function handles dark mode without `dark:` variants,\n  keeping component source theme-agnostic.\n- **Authoring rule (proven by the spike):** semantic-color utilities must carry\n  the `color:` type hint — `bg-[color:var(--kyla-base)]`,\n  `text-[color:var(--kyla-fg)]`, `border-[color:var(--kyla-line)]`. A bare\n  `bg-[var(--…)]` is type-ambiguous and Twind silently emits nothing (the\n  failure is invisible — no error, just an unstyled element). Lengths are\n  unambiguous, so `rounded-[var(--kyla-radius)]` needs no hint. Because the\n  omission fails silently, component authors must not hand-write these strings;\n  the `cn()`/variant layer should emit token utilities through a tiny helper so\n  the hint can never be forgotten.\n",[],[212,737,763],"5952a1d0-5e01-4609-a8ae-f86b41871f4b",15,["D",1781808698135],[229,230,231,232,233],[212,737],["D",1781808698019],[228,234,238,240,271,273],[212],["D",1781804868537],["D",1789701064442],{"_99":98,"_106":102},{"_99":98,"_100":-5,"_101":102,"_18":56,"_103":104,"_105":25},{"_13":88,"_32":89,"_44":43,"_90":45,"_91":-5,"_92":-5,"_93":-5,"_94":-5,"_95":-5,"_96":46,"_97":98},"ctx",{"_81":-5,"_127":816,"_817":818,"_819":820,"_821":25,"_822":25,"_823":25,"_824":125,"_825":-5,"_826":-7,"_827":-7,"_828":62,"_829":25,"_830":25,"_831":-5,"_832":25,"_833":25,"_834":25,"_835":-5},"ENV",{"_787":788,"_789":790,"_791":89,"_792":793,"_794":795,"_796":797,"_798":799,"_800":801,"_802":803,"_804":805,"_806":807,"_808":809,"_810":811,"_812":813,"_814":815},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
