This is\nthe hub: vocabulary lives in [`../CONTEXT.md`](../CONTEXT.md), and each\nconsequential decision has an ADR in [`adr/`](./adr/). This doc summarizes the\nshape and records what is **deliberately deferred**.\n\n> Modeled on [Cloudflare Kumo](https://github.com/cloudflare/kumo) — semantic\n> tokens, headless foundation, primitives + components — ported onto Val Town's\n> **no-build** reality. Where Kumo uses Tailwind v4 + codegen, Kylä uses runtime\n> 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\n below).\n- **Layout** — `src/` is split by concern (root re-export files hide it from\n consumers): `src/utils/` (framework-agnostic class helpers), `src/theme/`\n (tokens, token-class builders, theming runtime), `src/components/` (one file\n per component). `mod.ts` is the public barrel; a Radix component gets a root\n re-export file (e.g. `dialog.ts`) kept _out_ of the barrel (ADR-0002).\n- **Styling foundation** — built in `kyla-ui` and verified on the runtime:\n - `src/utils/cn.ts` — `twMerge(clsx())`, versions pinned (clsx@2.1.1,\n tailwind-merge@3.6.0); empirically confirmed to dedupe `[color:var(--…)]`\n token classes. Contract: `cn(componentClasses, className)` — caller's\n `className` wins.\n - `src/theme/tw.ts` — `tw.bg/text/border/ring/ringOffset(token, state?)`\n builders that bake in the `color:` hint (state-prefixable), plus the\n `ColorToken` union (typo = compile error).\n - `src/utils/variants.ts` — hand-rolled cva-style `variants()` (no external\n dep).\n - `src/theme/tokens.ts` — token stylesheet (provisional values).\n - `src/theme/provider.tsx` — `KylaProvider` + `useKylaMode`.\n - `mod.ts` — public barrel (Radix kept out).\n- **First component** — `src/components/button.tsx` (`Button`, `ButtonProps`):\n variants `primary | subtle | ghost | danger` × `sm | md | lg`, token focus\n ring, default `type=\"button\"`, forwarded ref + rest props, escape-hatch\n `className`. Verified by server-render. Surfaced + fixed a foundation gap:\n state-prefixed token utilities (`tw.bg(\"recessed\", \"hover\")`).\n- **Next** — real palette/scales; more components (`Card`, `Input`, `Text`, …);\n bring `Dialog` over to exercise the Radix-behind-its-own-path split.\n\n## Shape\n\n- **Two vals.**\n - `kyla-ui` — the importable library, which also serves its own\n **Gallery** (docs) at its HTTP route.\n - `kyla-ui-starter` — a remixable, genuine\n **todo app** (real HTTP route + `std/sqlite`) showing idiomatic end-to-end\n use. The Starter depends on the library; never the reverse.\n- **CSR-only for v1.** Target is interactive apps (dashboards, tools, forms)\n where SEO/first-paint don't matter. Components authored pure so isomorphic\n stays 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\n (`bg-[var(--kyla-base)]`). 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;\n build on a headless library only for hard interactive ones. **Radix first**\n (proven 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 `Popover`,\n `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()` +\n Provider. Radix primitives stay **internal** (so Radix→Base UI later isn't an\n API break).\n- **Accessibility (bounded):** correct semantic HTML, real\n ``/`id` association, token-based visible focus, no broken\n native keyboard behavior, AA contrast on the default theme. Anything needing\n 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:\n**`nbbaier/kyla-ui-spike`** (`frontend/{App,KylaProvider,tokens}.tsx`). All four\ngreen:\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\ninvisible, the `cn()`/variant layer must emit token utilities through a helper\nso authors can'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 fixed\n 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\n needed.\n",[],[396,389],"docs","8dab6582-02fc-404c-8075-20be76723447","2026-06-18-design-and-foundation.md","019f3953-b8df-70da-933b-0ead238cd3ee","019f3953-b8df-70da-933b-111bb9523094",["D",1783373215838],"# Handoff — Kylä UI design + foundation (2026-06-18)\n\nPicking up the `nbbaier/kyla-ui` component library for Val Town. This thread did the\ndesign grilling, proved the runtime substrate, and built the styling foundation + the\nfirst component (`Button`). This doc is a pointer map + \"what's next\", not a re-spec —\nthe 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, **Implementation\n status** section, open spikes (all ✅), and the \"Deliberately 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 dir via\n `vt`). `nbbaier/kyla-ui-spike` (throwaway substrate proof — all 4 spikes green\n 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`), `src/components/`\n (`button`). Layout rationale is in the sketch's 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 — `bg-[color:var(--…)]`,\n never `bg-[var(--…)]` (the latter silently renders nothing; no error). Always go\n through the `tw.*` builders in `src/theme/tw.ts`, which bake it in. (ADR-0001.)\n2. **Twind lives in the HTML shell**, not the Provider (must load before first paint).\n 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. (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 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 eyeball\n all variant/size combos + hover/focus in a browser. (Quick loop-closer.)\n2. **Real palette + structural scales** — replace provisional tokens with AA-checked\n surface/fg/border ramps + spacing/radius/type scales. Highest-leverage deferred item.\n3. **More components** — `Card`, `Text`/`Heading`, `Input`, `Textarea`, `Label`, `Badge`,\n `Stack`, `Box`, `Divider`, then native-styled `Select`. Reuse the Button pattern.\n4. **`Dialog` (Radix)** — first component behind its own import path: `src/components/dialog.tsx`\n + a root `dialog.ts` re-export, kept OUT of `mod.ts` (ADR-0002). Exercises the split.\n5. **Gallery** — the library's self-hosted docs HTTP route (CONTEXT.md → \"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` 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 `delete_file`\n it. Used twice this thread; clean and fast.\n- For anything UI/platform-specific on Val Town, pull the official skill via the valtown\n 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, view-source) for\n 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 Starter\n todo app and/or the Gallery route.\n- **rams** (or **impeccable**) — accessibility / visual-design review once there are\n enough components and the real palette to evaluate.\n",[],[396,405,398],"handoffs","4fcaf772-350f-455a-be01-06b6aa80fdf6",["D",1783373215838],[218],[396,405],"e694cb85-9e03-4583-80b7-36c6e28536bf","triage-labels.md","019f3953-b8df-70da-933b-07c96565ee56","019f3953-b8df-70da-933b-0ad85de5eb6d",["D",1783375727400],"# Triage Labels\n\nThe skills speak in terms of five canonical triage roles.
