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 \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 \n \n \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",[],[328],"b9424b06-37a8-4f88-b789-d02511d35f12","CONTEXT.md","019f624e-0dc9-701d-a888-892665900440",["D",1784060710350],"# 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",[],[335],"0dcecf1a-161c-4655-8d76-b01ecebf2ca0","CLAUDE.md","019f624e-0dc9-701d-a888-84e5bc5bd2b8",["D",1784061317926],4,"## 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/**` (specs, 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### Val Town branch workflow\n\n- Before starting, verify the checkout with `vt status`, then branch from the\n stable line with `vt checkout main` followed by\n `vt checkout -b -NN-`; use a short prefix derived from\n the spec/feature (for example, `scales-03-type-scale-and-font`).\n- Keep implementation work on that branch. `vt push` is the Val Town commit for\n the branch; finish by running `vt status` and confirming local state matches\n remote state.\n- A ticket is not landed when it is merely pushed to a work branch. Merge the\n branch into `main` to cut the next Release, then record the `Landed: vNNN`\n version and `Status: done` in the issue file.\n\n## Agent skills\n\n### Issue tracker\n\nIssues and specs live as local markdown files under\n`docs/issues//`; no external tracker. See\n`docs/agents/issue-tracker.md`.\n\n### Triage labels\n\nUses the default five-role label vocabulary unchanged (`needs-triage`,\n`needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`). See\n`docs/agents/triage-labels.md`.\n\n### Domain docs\n\nSingle-context layout: `CONTEXT.md` + `docs/adr/` at the repo root. See\n`docs/agents/domain.md`.\n",[],[342],"542e2dd9-710d-4535-b356-edd0766682b4","AGENTS.md","019f624e-0dc9-701d-a888-83ee5eac02d2",["D",1784061317926],[],[350],"13444988-b8b6-4420-a16b-53bd0a74e6da",".vtignore","019f624e-0dc9-701d-a888-7e872ba80e4f",["D",1784060710350],".git\n.vscode\n.cursor\n.DS_Store\nnode_modules\nvendor\n.claude",[],[356],"8896ffad-a39f-4db7-a888-19a9e26dee09","variants.ts","019f624e-0dc9-701d-a888-71c218a637da","019f624e-0dc9-701d-a888-75cf7c383351",["D",1784060710350],"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).
