This is the\nhub: vocabulary lives in [`../CONTEXT.md`](../CONTEXT.md), and each consequential\ndecision has an ADR in [`adr/`](./adr/). This doc summarizes the shape and records\nwhat is **deliberately deferred**.\n\n> Modeled on [Cloudflare Kumo](https://github.com/cloudflare/kumo) — semantic tokens,\n> headless foundation, primitives + components — ported onto Val Town's **no-build**\n> reality. Where Kumo uses Tailwind v4 + codegen, Kylä uses runtime CSS variables + Twind.\n\n## Positioning\n\n**Lead with consistency, not accessibility.** The felt pain for the Val Town\naudience (shipping apps fast, no designer) is inconsistent, hand-assembled UI.\nAccessibility is a real but *quiet, bounded* guarantee underneath. See\n[ADR-0003](./adr/0003-consistency-first-bounded-accessibility.md).\n\n## Implementation status\n\n- **Substrate spike** — `nbbaier/kyla-ui-spike`, all four spikes green (see below).\n- **Styling foundation** — built in `kyla-ui` and verified on the runtime:\n - `src/cn.ts` — `twMerge(clsx())`, versions pinned (clsx@2.1.1, tailwind-merge@3.6.0);\n empirically confirmed to dedupe `[color:var(--…)]` token classes. Contract:\n `cn(componentClasses, className)` — caller's `className` wins.\n - `src/theme.ts` — `tw.bg/text/border/ring(token)` builders that bake in the\n `color:` hint, plus the `ColorToken` union (typo = compile error).\n - `src/variants.ts` — hand-rolled cva-style `variants()` (no external dep).\n - `src/tokens.ts` — token stylesheet (provisional values).\n - `src/provider.tsx` — `KylaProvider` + `useKylaMode`.\n - `mod.ts` — public barrel (Radix kept out).\n- **Next** — real palette/scales, then the first component (`Button`).\n\n## Shape\n\n- **Two vals.** `kyla-ui` — the importable library, which also serves its own\n **Gallery** (docs) at its HTTP route. `kyla-ui-starter` — a remixable, genuine\n **todo app** (real HTTP route + `std/sqlite`) showing idiomatic end-to-end use.\n The Starter depends on the library; never the reverse.\n- **CSR-only for v1.** Target is interactive apps (dashboards, tools, forms) where\n SEO/first-paint don't matter. Components authored pure so isomorphic stays\n possible later, without paying its tax now.\n\n## Styling — [ADR-0001](./adr/0001-no-build-styling-architecture.md)\n\n- Semantic tokens as `--kyla-*` **CSS custom properties** using `light-dark()`;\n applied via runtime **Twind arbitrary-value** utilities (`bg-[var(--kyla-base)]`).\n No build, no bundler.\n- Token vocabulary: surfaces `base → elevated → recessed`; foreground `fg`,\n `fg-muted`; borders `line`, `hairline`; `accent`, `danger`; `radius`.\n- One opinionated theme. Small consumer **override surface** (`--kyla-accent`,\n `--kyla-radius`, font); structural tokens stay fixed — that fixedness *is* the\n consistency. A Kumo-style named-theme system is a deliberate later step.\n\n## Style delivery & theming\n\n- **`KylaProvider`** guarantees Twind + token stylesheet are present (a manual\n two-tag `` setup is the documented fallback).\n- The Provider **owns Mode**: sets `data-mode=\"light|dark|system\"`, exposes\n `useKylaMode()` (persistence opt-in); `system` falls through to OS via\n `light-dark()`. Apps get a first-class light/dark toggle for free.\n\n## Components — [ADR-0002](./adr/0002-hybrid-headless-foundation.md)\n\n- **Hybrid foundation.** Hand-roll simple visual components with zero deps; build\n on a headless library only for hard interactive ones. **Radix first** (proven\n on VT), Base UI as a likely faithful-to-Kumo later variant.\n- **v1 inventory:**\n - Zero-dep visual: `Button`, `Text`/`Heading`, `Card`, `Input`, `Textarea`,\n `Label`, `Badge`, `Stack`, `Box`, `Divider`\n - Styled native: `Select`\n - Radix-backed (the headless proof): `Dialog`\n - Deferred to v1.1+: `Checkbox`, `Radio`, `Spinner`, `Alert`, then\n `Popover`, `Menu`, `Tabs`, `Tooltip`, `Combobox`, `Toast`, `Table`, …\n- **API:** typed **variant** props (`variant`, `size`, `tone`) mapping to tokens\n internally; escape-hatch `className` merged last via exported `cn()`; refs +\n rest props forwarded. Public surface = finished components + `cn()` + Provider.\n Radix primitives stay **internal** (so Radix→Base UI later isn't an API break).\n- **Accessibility (bounded):** correct semantic HTML, real ``/`id`\n association, token-based visible focus, no broken native keyboard behavior,\n AA contrast on the default theme. Anything needing custom ARIA → Radix tier.\n\n## Distribution — [ADR-0004](./adr/0004-version-pinned-upgrade-contract.md)\n\n- **Module layout:** barrel `mod.ts` for the zero-dep core; heavy `dialog.tsx`\n behind its own import path so Radix only loads when used.\n- **Upgrade contract:** `main` is the release line; development happens on\n branches; a **Release** is a merge to `main`. Unpinned import = latest Release\n (fixes auto-propagate); `?v=NNN` to freeze; README release table maps names →\n versions. (esm.town has no branch-import URLs, hence version pinning.)\n\n## Open verification spikes\n\nBuilt and **fully verified in-browser** as one throwaway val: **`nbbaier/kyla-ui-spike`**\n(`frontend/{App,KylaProvider,tokens}.tsx`). All four green:\n\n1. ✅ **Radix `Dialog`** — imports via esm.sh with React 18.2.0 (the\n `?deps=react@18.2.0,react-dom@18.2.0` pin propagates through Radix's whole\n transitive graph, defusing the React-mismatch `useState` null error) and\n renders/opens/closes/focus-traps cleanly under CSR.\n2. ✅ **Twind + CSS-var tokens** — surfaces render stepped, accent applies.\n3. ✅ **`KylaProvider` runtime token injection** — styles exist only because the\n Provider injected the stylesheet. (Twind stays in the *shell* since it must\n load before first paint; only the token stylesheet is Provider-injected.)\n4. ✅ **`light-dark()` + `data-mode`** — mode toggle flips the palette; resolves\n even inside the Radix portal.\n\n### Load-bearing finding (the spike's main payoff)\n\nOn Val Town's runtime **Twind, semantic-color utilities must carry the `color:`\ntype hint** — `bg-[color:var(--kyla-base)]`, `text-[color:var(--kyla-fg)]`,\n`border-[color:var(--kyla-line)]`. A bare `bg-[var(--…)]` is type-ambiguous and\nTwind **silently emits nothing** — no error, just an unstyled element. Lengths\nare fine bare (`rounded-[var(--kyla-radius)]`). Because the failure is invisible,\nthe `cn()`/variant layer must emit token utilities through a helper so authors\ncan't forget the hint. (Baked into ADR-0001.)\n\n## Deliberately deferred (not yet designed)\n\nThese were identified but intentionally not resolved in this sketch. The\n**spacing / radius / type scale** is the highest-leverage — it's where visual\nconsistency actually lives.\n\n- **Structural scales** — the spacing, radius, and typographic scales (the\n fixed tokens carrying most of the consistency). Currently undefined.\n- **Variant→token maps** — concrete `variant`/`size`/`tone` value sets per\n component (e.g. what tones `Button`/`Badge` expose).\n- **`KylaProvider` API** — its precise prop surface beyond \"owns styles + Mode\".\n- **Gallery generation** — hand-written vs generated from component metadata.\n- **Theming v2** — a Kumo-style named-theme system (multiple consumer-defined\n themes) once there's demand.\n- **Base UI variant** — a Base-UI-backed build once Radix proves the path.\n- **Isomorphic rendering** — SSR + hydration for content/landing pages, if needed.\n","# Kylä UI — v1 Design Sketch\n\nA high-level sketch of the v1 design, produced from a design interview.

Town.",[170],"c0337397-a3af-4f93-884e-f82ce0cfb4e8","CONTEXT.md","bce56486-6b46-11f1-8898-1607ee4eb77e",23,["D",1781813006665],"# Kylä UI — Context\n\nA glossary of the core terms in this project. Implementation details live in code 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 React components, a styling system, and any helpers needed to build consistently styled web apps. It is **consumed by import** (`import { ... } from \"https://esm.town/v/nbbaier/kyla-ui/...\"`), not by remixing. This val is the source of truth for visual consistency across apps. It **also serves its own Gallery** (docs) at its HTTP route — the library documents itself, co-located with its source.\n\n### Starter\n\nA separate, remixable demo val (`kyla-ui-starter` or similar) that shows idiomatic *end-to-end* use of Kylä UI: a tiny but genuine **todo app** with a real HTTP route and `std/sqlite`, a working app shell, Provider + hydration wiring, and view-source link. A new app begins by remixing the Starter, then editing. The Starter **depends on** Kylä UI; the library never depends on the Starter. (Component reference/docs live in the library's Gallery, not the Starter.)\n\n### Gallery\n\nThe library's self-hosted documentation surface: an HTTP route on `kyla-ui` that renders every component in its variants and Modes, with the Mode toggle. It is both living docs and the in-browser proof that the stack renders correctly on Val Town (Twind + CSS-var tokens, Provider mode, Radix `Dialog` hydration). The seed of a fuller docs site later.\n\n### Release\n\nA blessed version of Kylä UI, produced by merging a development branch into `main`. `main` is the stable line: raw development never happens on it, so HEAD-of-`main` is always a Release. Each Release corresponds to a concrete Val Town version number (`?v=NNN`). A consumer tracks Releases by importing the unpinned URL (always latest Release) or freezes onto one by pinning its `?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 library rather than copying its code.\n\n### Semantic Token\n\nA named, intent-based design value (e.g. \"base surface,\" \"default foreground,\" \"line/border,\" \"danger\") rather than a raw value (e.g. \"blue-500\"). Components reference semantic tokens only; they never hard-code raw colors. Tokens are the unit of visual consistency and the surface through which a Theme is applied. (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 / status:** `accent`, `danger` (and siblings as needed)\n- **Shape:** `radius`\n\nOf these, the consumer-facing Override Surface for v1 is intentionally small (e.g. `--kyla-accent`, `--kyla-radius`, font); the rest are structural and stay fixed.\n\n### Theme\n\nA complete set of values bound to the Semantic Tokens, producing a coherent look. A consumer switches the active theme without touching component code. Light/dark is one axis of theming; brand/variant overrides are another.\n\nFor v1, Kylä ships **one opinionated theme** with automatic light/dark, and exposes a deliberately small **Override Surface** — a few tokens (e.g. accent, radius, font) a consumer may redefine to express brand. Structural tokens (surface hierarchy, spacing, borders) stay fixed; that fixedness *is* the consistency. A fuller named-theme system (multiple consumer-defined Themes, à la Kumo'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. `variant=\"primary\"`, `size=\"sm\"`, `tone=\"danger\"`). Variants map to Semantic Tokens internally; they are the consumer's primary, discoverable means of varying a component while staying on-system. An escape-hatch `className` always merges last, letting an app deviate locally without forking. For v1 the public surface is finished components plus a `cn()` helper and the Provider — the underlying Headless Primitives stay internal.\n\n### Mode\n\nThe light/dark axis of a Theme. Modeled as `data-mode=\"light\" | \"dark\" | \"system\"`, where `system` falls through to the OS preference via CSS `light-dark()` (zero JS). Mode is **owned by the Provider** — it sets `data-mode` and exposes a hook to read/set it (persistence opt-in) — so apps get a first-class light/dark toggle without hand-rolling one (a common source of inconsistency and flash-of-wrong-theme bugs).\n\n### Headless Primitive\n\nThe behavior-and-accessibility layer of an interactive component (focus management, keyboard nav, ARIA), independent of its visual styling. For the hard interactive components (Dialog, Popover, Menu, Tabs), Kylä builds on a third-party headless primitive library rather than hand-rolling. Simple visual components (Button, Card, Stack, Text, Input, Badge) have no separate Headless Primitive — they are styled directly.\n\n",[177],"1c7f3876-c7c1-4d67-8ed9-16bd851ecf3f",".vtignore","47ce4d8c-6b3e-11f1-8eca-1607ee4eb77e",13,["D",1781805649048],".git\n.vscode\n.cursor\n.DS_Store\nnode_modules\nvendor\n.claude",[184],"da3f4f02-c070-4df1-9bc5-96c25fc6eefd","src","91e38b30-6b52-11f1-bb7a-1607ee4eb77e",28,["D",1781813780417],"directory",[191],"61b715f9-32d9-45da-bff6-008ae80a2386","docs","bc8b0c5c-6b46-11f1-aeb1-1607ee4eb77e",14,["D",1781808698019],[198],"pulls","branches",7,"forks","envVars",{"_211":62,"_213":62},"connections",{"_211":62,"_212":62},"count","unfilledCount","emptyCount",{"_44":197,"_33":198,"_31":199,"_141":-5,"_42":43,"_41":200,"_143":25,"_39":352,"_13":62,"_35":195,"_36":-5,"_24":27,"_148":-5,"_236":353,"_28":354},{"_44":347,"_33":321,"_31":315,"_141":199,"_42":43,"_41":348,"_143":25,"_39":349,"_13":62,"_35":195,"_36":-5,"_24":27,"_148":-5,"_236":350,"_28":351},{"_44":338,"_33":339,"_31":340,"_141":315,"_42":43,"_41":341,"_143":27,"_39":342,"_13":343,"_35":20,"_36":344,"_24":27,"_148":-5,"_236":345,"_28":346},{"_44":330,"_33":331,"_31":332,"_141":315,"_42":43,"_41":333,"_143":27,"_39":334,"_13":62,"_35":20,"_36":335,"_24":27,"_148":-5,"_236":336,"_28":337},{"_44":322,"_33":323,"_31":324,"_141":315,"_42":43,"_41":325,"_143":27,"_39":326,"_13":62,"_35":20,"_36":327,"_24":27,"_148":-5,"_236":328,"_28":329},{"_44":312,"_33":313,"_31":314,"_141":315,"_42":43,"_41":316,"_143":27,"_39":317,"_13":62,"_35":20,"_36":318,"_24":27,"_148":-5,"_236":319,"_28":320},{"_44":308,"_33":34,"_31":32,"_141":199,"_42":43,"_41":14,"_143":27,"_39":309,"_13":172,"_35":20,"_36":38,"_24":27,"_148":-5,"_236":310,"_28":311},{"_44":190,"_33":191,"_31":192,"_141":-5,"_42":43,"_41":193,"_143":25,"_39":305,"_13":62,"_35":195,"_36":-5,"_24":27,"_148":-5,"_236":306,"_28":307},{"_44":297,"_33":298,"_31":299,"_141":192,"_42":43,"_41":300,"_143":27,"_39":301,"_13":172,"_35":146,"_36":302,"_24":27,"_148":-5,"_236":303,"_28":304},{"_44":289,"_33":290,"_31":291,"_141":192,"_42":43,"_41":292,"_143":27,"_39":293,"_13":62,"_35":146,"_36":294,"_24":27,"_148":-5,"_236":295,"_28":296},{"_44":281,"_33":282,"_31":283,"_141":192,"_42":43,"_41":284,"_143":27,"_39":285,"_13":62,"_35":146,"_36":286,"_24":27,"_148":-5,"_236":287,"_28":288},{"_44":273,"_33":274,"_31":275,"_141":192,"_42":43,"_41":276,"_143":27,"_39":277,"_13":145,"_35":146,"_36":278,"_24":27,"_148":-5,"_236":279,"_28":280},{"_44":265,"_33":266,"_31":267,"_141":192,"_42":43,"_41":268,"_143":27,"_39":269,"_13":62,"_35":146,"_36":270,"_24":27,"_148":-5,"_236":271,"_28":272},{"_44":257,"_33":258,"_31":259,"_141":192,"_42":43,"_41":260,"_143":27,"_39":261,"_13":62,"_35":146,"_36":262,"_24":27,"_148":-5,"_236":263,"_28":264},{"_44":183,"_33":184,"_31":185,"_141":-5,"_42":43,"_41":186,"_143":25,"_39":254,"_13":145,"_35":20,"_36":188,"_24":27,"_148":-5,"_236":255,"_28":256},{"_44":176,"_33":177,"_31":178,"_141":-5,"_42":43,"_41":179,"_143":27,"_39":251,"_13":172,"_35":20,"_36":181,"_24":27,"_148":-5,"_236":252,"_28":253},{"_44":169,"_33":170,"_31":171,"_141":-5,"_42":43,"_41":172,"_143":27,"_39":248,"_13":145,"_35":20,"_36":174,"_24":27,"_148":-5,"_236":249,"_28":250},{"_44":162,"_33":163,"_31":164,"_141":-5,"_42":43,"_41":165,"_143":27,"_39":245,"_13":145,"_35":20,"_36":167,"_24":27,"_148":-5,"_236":246,"_28":247},{"_44":155,"_33":156,"_31":157,"_141":-5,"_42":43,"_41":158,"_143":27,"_39":242,"_13":145,"_35":20,"_36":160,"_24":27,"_148":-5,"_236":243,"_28":244},{"_44":150,"_33":151,"_31":152,"_141":-5,"_42":43,"_41":145,"_143":27,"_39":239,"_13":62,"_35":146,"_36":108,"_24":27,"_148":-5,"_236":240,"_28":241},{"_44":138,"_33":139,"_31":140,"_141":-5,"_42":43,"_41":142,"_143":27,"_39":235,"_13":145,"_35":146,"_36":147,"_24":27,"_148":-5,"_236":237,"_28":238},["D",1781814189001],"children",[],[139],["D",1781804868548],[],[151],["D",1781805628403],[],[156],["D",1781805628422],[],[163],["D",1781804941550],[],[170],["D",1781813006665],[],[177],["D",1781805649048],[],[184],"a88539c6-46fe-4845-a806-43b03dc6c285","variants.ts","92020682-6b52-11f1-80b8-1607ee4eb77e",30,["D",1781813780594],"import { cn } from \"./cn.ts\";\n\ntype VariantShape = Record>;\ntype Selection = { [K in keyof V]?: keyof V[K] };\n\n/**\n * Minimal cva-style helper: maps typed variant props to token-based class strings.\n *\n * Hand-rolled to avoid an external dependency (per ADR-0002's keep-the-common-case\n * dependency-free posture).
