+# nychthemeron
+
+A CSS-reactive Vue component library built on PrimeVue (Unstyled), shipped with the nychthemeron theme as a default.
+
+## About
+
+nychthemeron provides a curated set of Vue 3 components powered by PrimeVue's unstyled components and the nychthemeron theme system. This approach gives you complete control over component styling while maintaining a consistent, polished design language out of the box.
+
+### Features
+
+- **CSS-Reactive**: Components respond to CSS changes without requiring JavaScript updates
+- **PrimeVue Powered**: Built on the robust, accessible PrimeVue unstyled component library
+- **Theme Included**: Ships with the nychthemeron theme, ready to use immediately
+- **TypeScript**: Full type support for Vue 3 and TypeScript projects
+- **Customizable**: Override or extend the default theme to match your design system
+
+## Quick Start
+
+### Installation
+
+```bash
+npm install @nychthemeron/library primevue vue@^3.5.0
+```
+
+### Basic Usage
+
+Import the library components and styles:
+
+```vue
+<script setup lang="ts">
+import { NychButton } from '@nychthemeron/library'
+</script>
+
+<template>
+  <NychButton label="Click me" />
+</template>
+
+<style>
+@import '@nychthemeron/library/style';
+@import '@nychthemeron/library/theme';
+</style>
+```
+
+## Components
+
+- **NychButton** - Customizable button component
+
+More components coming soon.
+
+## Customization
+
+### Using the Default Theme
+
+The nychthemeron theme is included by default:
+
+```css
+@import '@nychthemeron/library/theme';
+```
+
+### Custom Styling
+
+Override or extend component styles by importing only the base styles and providing your own CSS:
+
+```css
+@import '@nychthemeron/library/style';
+
+/* Your custom theme */
+:root {
+  --primary-color: #your-color;
+  /* More CSS variables */
+}
+```
+
+## Project Structure
+
+This is a monorepo containing:
+
+- **`packages/library`** - The component library package
+- **`packages/playground`** - Development environment and examples
+
+## Development
+
+### Setup
+
+```bash
+bun install
+```
+
+### Development Server

+# Library with Playground Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Transform nychthemeron into a monorepo with a Vue component library (with PrimeVue + Tailwind) and interactive Storybook playground.
+
+**Architecture:** Bun workspaces manage two independent packages — library (builds to ESM) and playground (Storybook dev server and static build). Shared configs at root level.
+
+**Tech Stack:** Vue 3, PrimeVue, Tailwind CSS, Vite, Storybook, Vitest, TypeScript, Bun workspaces
+
+---
+
+### Task 1: Create monorepo directory structure
+
+**Files:**
+- Create: `packages/library/` directory
+- Create: `packages/playground/` directory
+
+- [ ] **Step 1: Create packages directories**
+
+```bash
+mkdir -p packages/library/src/{components,composables}
+mkdir -p packages/library/__tests__
+mkdir -p packages/playground/.storybook
+mkdir -p packages/playground/stories
+```
+
+- [ ] **Step 2: Verify structure**
+
+```bash
+ls -la packages/
+# Expected output shows: library/ and playground/ directories
+```
+
+---
+
+### Task 2: Move existing source to library package
+
+**Files:**
+- Move: `src/` → `packages/library/src/`
+- Delete: `vite.config.ts`, `vitest.config.ts`, `index.html` (will recreate in packages)
+
+- [ ] **Step 1: Move src directory**
+
+```bash
+mv src packages/library/src
+```
+
+- [ ] **Step 2: Verify move**
+
+```bash
+ls packages/library/src/
+# Expected: App.vue, main.ts, __tests__/
+```
+
+- [ ] **Step 3: Delete old root-level config files**
+
+```bash
+rm vite.config.ts vitest.config.ts index.html
+```
+
+---
+
+### Task 3: Update root package.json for monorepo

+## Self-Review
+
+**Spec coverage:**
+- ✅ Monorepo structure (Task 1)
+- ✅ Bun workspaces setup (Tasks 2-3)
+- ✅ Library package creation (Tasks 4-8)
+- ✅ Composables structure (Task 8)
+- ✅ Playground/Storybook setup (Tasks 9-15)
+- ✅ Tailwind integration (Tasks 11, 14)
+- ✅ PrimeVue initialization (Task 13)
+- ✅ Dev workflow verification (Task 17)
+- ✅ Build verification (Task 18)
+- ✅ Git initialization (Task 19)
+
+**Placeholder scan:** No TBDs, "fill in later", incomplete steps. All code blocks are complete and exact.
+
+**Type consistency:** Package names consistent (`@nychthemeron/library`, `@nychthemeron/playground`). All import paths and config keys match across tasks.
+
+**Scope:** Plan produces working, testable monorepo. Library builds to `dist/`, Storybook starts and loads stories. Next phase (adding components) is separate.

+# Docs Site Docker Image + Install Page Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add an Installation page to the Storybook playground, package the playground's static build as a `nychthemeron-docs` Docker image served by nginx, and wire up CI to build/push that image on version tags.
+
+**Architecture:** A new MDX docs page (`packages/playground/stories/Install.mdx`) documents installing `@nychthemeron/library` via npm/pnpm/yarn/bun from the private Forgejo npm registry. A new multi-stage `packages/playground/Dockerfile` builds the library and Storybook static output with `oven/bun:1`, then copies `storybook-static` into `nginx:alpine`. A root `.dockerignore` keeps the build context lean. A new `publish-docs` job in `.forgejo/workflows/ci.yml`, parallel to `publish`, builds and pushes the image on `v*` tags.
+
+**Tech Stack:** Storybook 10 (`@storybook/addon-docs`), Vue 3, Bun, Docker (multi-stage, nginx:alpine), Forgejo Actions.
+
+---
+
+### Task 1: Add Installation MDX page
+
+**Files:**
+- Create: `packages/playground/stories/Install.mdx`
+
+- [ ] **Step 1: Create the MDX file**
+
+```mdx
+import { Meta } from '@storybook/addon-docs/blocks'
+
+<Meta title="Get Started/Installation" />
+
+# Installation
+
+`@nychthemeron/library` is published to a private npm registry hosted on
+Forgejo. Configure your package manager for the `@nychthemeron` scope, then
+install the package.
+
+## Configure the registry
+
+Add the following to your project's `.npmrc`:
+
+```
+@nychthemeron:registry=https://git.mcpeakdev.com/api/packages/mcpeakdev/npm/
+```
+
+## npm
+
+```bash
+npm install @nychthemeron/library
+```
+
+## pnpm
+
+```bash
+pnpm add @nychthemeron/library
+```
+
+## yarn
+
+```bash
+yarn add @nychthemeron/library
+```
+
+## bun
+
+```bash
+bun add @nychthemeron/library
+```
+```
+
+- [ ] **Step 2: Build Storybook and verify the page is included**
+
+Run: `cd packages/playground && bun run build`
+
+Expected: Build succeeds with output ending in something like
+`Output directory: storybook-static`. Then run:
+
+`grep -o '"title":"Get Started/Installation"' packages/playground/storybook-static/index.json`
+
+Expected: prints `"title":"Get Started/Installation"`.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add packages/playground/stories/Install.mdx
+git commit -m "Add installation docs page to playground"
+```
+
+---
+
+### Task 2: Add root `.dockerignore`
+
+**Files:**
+- Create: `.dockerignore`
+
+- [ ] **Step 1: Create `.dockerignore`**
+
+```
+node_modules
+**/node_modules
+**/dist
+**/storybook-static
+**/.storybook-static
+.git
+docs
+.tmp
+.bun-cache
+.pw-browsers
+.pw-libs
+.shots
+*.log
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add .dockerignore
+git commit -m "Add .dockerignore for docs Docker build"
+```
+
+---
+
+### Task 3: Add Dockerfile for the docs site
+
+**Files:**
+- Create: `packages/playground/Dockerfile`
+
+- [ ] **Step 1: Create the Dockerfile**
+
+```dockerfile
+# syntax=docker/dockerfile:1
+
+FROM oven/bun:1 AS build
+WORKDIR /app
+COPY . .
+RUN bun install --frozen-lockfile
+RUN cd packages/library && bun run build
+RUN cd packages/playground && bun run build
+
+FROM nginx:alpine AS runtime
+COPY --from=build /app/packages/playground/storybook-static /usr/share/nginx/html
+EXPOSE 80
+```
+
+- [ ] **Step 2: Build and run the image locally**
+
+Run (from repo root):
+
+```bash
+docker build -t nychthemeron-docs:test -f packages/playground/Dockerfile .
+docker run -d --rm --name nychthemeron-docs-test -p 8080:80 nychthemeron-docs:test
+sleep 2
+curl -sf http://localhost:8080/ | grep -i storybook
+docker stop nychthemeron-docs-test
+```
+
+Expected: `docker build` completes successfully, the container starts, and
+the `curl` output contains a reference to `storybook` (from
+`storybook-static/index.html`).
+
+> If the Docker CLI/daemon isn't available in the current environment (e.g.
+> sandboxed dev container), skip running this step here and ask the user to
+> run it locally before merging.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add packages/playground/Dockerfile
+git commit -m "Add Dockerfile for nychthemeron-docs static site"
+```
+
+---
+
+### Task 4: Add `publish-docs` CI job
+
+**Files:**
+- Modify: `.forgejo/workflows/ci.yml`
+
+- [ ] **Step 1: Add the `publish-docs` job**
+
+Add this job after the existing `publish` job (same indentation level,
+i.e. as a sibling under `jobs:`):
+
+```yaml
+    publish-docs:
+        needs: build
+        if: startsWith(github.ref, 'refs/tags/v')
+        runs-on: docker
+        steps:
+            - name: Checkout
+              uses: actions/checkout@v4
+
+            - name: Log in to registry
+              uses: docker/login-action@v3
+              with:
+                  registry: git.mcpeakdev.com
+                  username: ${{ github.actor }}
+                  password: ${{ secrets.FORGEJO_TOKEN }}
+
+            - name: Extract image tag
+              id: meta
+              run: echo "tag=${GITHUB_REF_NAME#v}" >> "$GITHUB_OUTPUT"
+
+            - name: Build and push docs image
+              uses: docker/build-push-action@v6
+              with:
+                  context: .
+                  file: packages/playground/Dockerfile
+                  push: true
+                  tags: |
+                      git.mcpeakdev.com/mcpeakdev/nychthemeron-docs:${{ steps.meta.outputs.tag }}
+                      git.mcpeakdev.com/mcpeakdev/nychthemeron-docs:latest
+```
+
+- [ ] **Step 2: Verify YAML structure**
+
+Run: `bun run --eval "console.log('ok')"` is not a YAML check — instead,
+visually confirm in the file that `publish-docs:` is indented exactly like
+`publish:` (4 spaces under `jobs:`), and that all of its child keys
+(`needs`, `if`, `runs-on`, `steps`, and each `- name:` step) match the
+indentation pattern used by the `publish` job. Confirm there are exactly
+three top-level jobs: `build`, `publish`, `publish-docs`.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add .forgejo/workflows/ci.yml
+git commit -m "Add publish-docs job to build and push nychthemeron-docs image"
+```

+# Library with Playground Design
+**Date:** 2026-05-11  
+**Project:** nychthemeron  
+**Status:** Approved
+
+## Overview
+
+Transform nychthemeron from a single Vue app into a monorepo containing a Vue component library built on PrimeVue with Tailwind CSS styling, accompanied by a Storybook playground for interactive documentation and development.
+
+## Goals
+
+- Build a reusable Vue component library with custom Tailwind-based styling on PrimeVue
+- Provide interactive documentation via Storybook for developers and stakeholders
+- Enable fast, hot-reload development workflow
+- Support both components and composables (e.g., date utilities for DatePicker)
+- Keep internal/private — no npm publishing required
+
+## Architecture
+
+### Monorepo Structure

+```
+
+### Dependency Model
+
+- **Root:** Shared dev dependencies (TypeScript, ESLint, Prettier, bun workspace config)
+- **Library:** Declares PrimeVue, Vue 3 as peer dependencies; exports components + composables
+- **Playground:** Imports `@nychthemeron/library` and PrimeVue; bundles Storybook
+
+### Technology Stack
+
+| Layer | Technology |
+|-------|-----------|
+| Framework | Vue 3 |
+| Component Base | PrimeVue |
+| Styling | Tailwind CSS + custom CSS layer |
+| Build (Library) | Vite (library mode) |
+| Build (Playground) | Vite + Storybook |
+| Testing | Vitest + Vue Test Utils |
+| Package Manager | Bun (with workspaces) |
+| Type Checking | TypeScript + vue-tsc |
+
+## Library Package Details
+
+### Export Model
+
+**index.ts** exports all components and composables:
+```typescript
+export * from './components'
+export * from './composables'
+```
+
+Consumers import as:
+```typescript
+import { DatePicker, Button } from '@nychthemeron/library'
+import { useDate } from '@nychthemeron/library'
+```
+
+### Component Structure
+
+Each component lives in its own folder:
+```
+src/components/
+├── DatePicker/
+│   ├── DatePicker.vue
+│   └── DatePicker.spec.ts
+├── Button/
+│   ├── Button.vue
+│   └── Button.spec.ts
+└── index.ts
+```
+
+### Composables Structure
+
+Reusable logic in `src/composables/`:
+```
+src/composables/
+├── useDate.ts          # Date utilities (parsing, formatting, etc.)
+├── index.ts
+```
+
+Components use composables internally; consumers can also import them directly.
+
+### Tailwind Integration
+
+- `tailwind.config.ts` extends PrimeVue theme with custom utilities
+- Library does NOT bundle Tailwind — consumers must include it in their setup
+- Supports portability: teams can apply custom Tailwind themes independently
+
+### Build Output
+
+- ESM modules (primary) + optional CommonJS
+- TypeScript declarations (`.d.ts`)
+- Sourcemaps for debugging
+- No dependency bundling (peer deps only)
+
+## Playground Package Details
+
+### Storybook Configuration
+
+- **Addon:** Vue 3 builder
+- **Global Setup:** `preview.ts` configures:
+  - Tailwind CSS
+  - PrimeVue theme setup
+  - Global styles
+- **Stories Location:** `stories/` directory
+
+### Story Structure
+
+Each component gets a `.stories.ts` file:
+```typescript
+// stories/DatePicker.stories.ts
+import DatePicker from '../components/DatePicker.vue'
+
+export default {
+  component: DatePicker,
+  tags: ['autodocs'],
+}
+
+export const Default = {}
+export const WithCustomTheme = { args: { /* ... */ } }
+```
+
+Stories serve triple duty:
+1. Interactive documentation for developers
+2. Visual regression baseline
+3. Live testing environment during dev
+
+### Preview Configuration
+
+`preview.ts` sets up:
+- Tailwind CSS
+- PrimeVue initialization
+- Global CSS imports
+- Example theme configuration
+
+## Development Workflow
+
+### Scripts
+
+**Root-level (`bun` commands):**
+```json
+{
+  "dev": "bun -r --cwd packages/playground dev",
+  "build": "bun -r --cwd packages/library build && bun -r --cwd packages/playground build",
+  "lint": "eslint packages/*/src",
+  "type-check": "vue-tsc --build",
+  "test": "bun -r --cwd packages/library test:unit"
+}
+```
+
+**Library scripts:**
+- `bun dev` — (unused for lib, optional for local testing)
+- `bun build` — Vite library build
+- `bun test:unit` — Vitest
+
+**Playground scripts:**
+- `bun dev` — Start Storybook dev server (port 6006)
+- `bun build` — Build static Storybook site
+
+### Developer Experience
+
+1. **Start playground:** `bun dev` (root) → Storybook on `localhost:6006`
+2. **Edit component:** Modify `packages/library/src/components/DatePicker/DatePicker.vue`
+3. **See update:** Playground hot-reloads via Storybook
+4. **View story:** Open `stories/DatePicker.stories.ts` to add/update examples
+5. **Test:** Run `bun test` in library package
+
+### Hot Reload
+
+- Library changes trigger Storybook rebuild
+- Playground imports `@nychthemeron/library` from source (no build step during dev)
+
+## Testing Strategy
+
+### Unit Tests
+
+- **Location:** `packages/library/__tests__/`
+- **Framework:** Vitest + Vue Test Utils
+- **Coverage:** Component logic, composables, edge cases
+- **Command:** `bun test` (from library or root)
+
+### Visual Documentation
+
+- Storybook stories serve as visual baseline
+- Can be extended with snapshot testing if needed
+
+### Type Safety
+
+- `vue-tsc --build` runs across monorepo
+- CI/local checks ensure no type errors
+
+## Build & Deployment
+
+### Library Build
+
+- **Output:** `packages/library/dist/`
+- **Formats:** ESM (primary) + optional CommonJS
+- **Declarations:** Full TypeScript support
+- **Size:** Optimized with tree-shaking enabled
+
+### Playground Build
+
+- **Output:** `packages/playground/storybook-static/`
+- **Deploy:** Can be served on internal server, wiki, or documentation site
+- **Audience:** Internal team, stakeholders, designers
+
+### Internal Distribution
+
+No npm publishing. Teams use library by:
+- Cloning/pulling monorepo
+- Installing dependencies: `bun install`
+- Importing components from `@nychthemeron/library`
+
+## Dependencies
+
+### Library Package
+
+**Peer Dependencies:**
+- `vue@^3.5.0`
+- `primevue@^18.0.0` (or latest)
+
+**Dev Dependencies:** (shared from root)
+- TypeScript, Vite, ESLint, Prettier
+
+### Playground Package
+
+**Dependencies:**
+- `@nychthemeron/library` (local workspace package)
+- `primevue`
+- `vue`
+
+**Dev Dependencies:**
+- Storybook (@storybook/vue3)
+- Vite, TypeScript
+
+## Success Criteria
+
+- ✅ Monorepo structure set up with bun workspaces
+- ✅ Library builds to `dist/` with exports
+- ✅ Storybook starts with `bun dev` and hot-reloads on library changes
+- ✅ Components use PrimeVue + Tailwind CSS
+- ✅ Composables (e.g., `useDate`) are accessible
+- ✅ TypeScript declarations present and correct
+- ✅ Unit tests run and pass
+- ✅ Shared config (ESLint, Prettier, tsconfig) enforced across packages
+
+## Next Steps
+
+1. Restructure project into monorepo layout
+2. Set up bun workspaces in root `package.json`
+3. Create library package with Vite lib config
+4. Create playground package with Storybook
+5. Add shared configurations
+6. Implement first component (e.g., Button or DatePicker)
+7. Create corresponding Storybook stories
+8. Test hot-reload workflow

+# Docs site (playground) Docker image + install page
+
+## Goal
+
+Publish the Storybook playground as a static "docs" site, package it as a
+Docker image (`nychthemeron-docs`), and add an Installation page documenting
+how to install `@nychthemeron/library` from the private Forgejo npm registry
+via npm, pnpm, yarn, and bun.
+
+## Install page
+
+- New file: `packages/playground/stories/Install.mdx`
+- Storybook addon-docs MDX page (no story export), `Meta` title
+  `Get Started/Installation` so it sorts near the top of the sidebar.
+- Content:
+  - Heading + short description of the library.
+  - Registry config snippet (`.npmrc`) showing how to point the scoped
+    `@nychthemeron` registry at `https://git.mcpeakdev.com/api/packages/mcpeakdev/npm/`.
+  - Four code blocks showing install commands for `@nychthemeron/library`:
+    npm, pnpm, yarn, bun.
+
+## Docker image (`nychthemeron-docs`)
+
+- New file: `packages/playground/Dockerfile`, multi-stage build:
+  - **Stage 1 (`oven/bun:1`)**: copy the workspace, `bun install --frozen-lockfile`,
+    build `@nychthemeron/library` (`cd packages/library && bun run build`),
+    then build Storybook (`cd packages/playground && bun run build` →
+    `packages/playground/storybook-static`).
+  - **Stage 2 (`nginx:alpine`)**: copy `storybook-static` into
+    `/usr/share/nginx/html`, default nginx config, `EXPOSE 80`.
+- Build context is the repo root (so the workspace lockfile and all
+  packages are available to stage 1).
+
+## CI changes
+
+In `.forgejo/workflows/ci.yml`, add a new `publish-docs` job:
+
+- Parallel to the existing `publish` job (both depend on `build`).
+- Gated on `startsWith(github.ref, 'refs/tags/v')`.
+- Steps:
+  1. Checkout
+  2. Log in to `git.mcpeakdev.com` using `docker/login-action` with
+     `secrets.FORGEJO_TOKEN` (same credential as the library publish job).
+  3. Extract version from tag (`${GITHUB_REF_NAME#v}`).
+  4. `docker/build-push-action` with context `.`, dockerfile
+     `packages/playground/Dockerfile`, push `true`, tags:
+     - `git.mcpeakdev.com/mcpeakdev/nychthemeron-docs:<version>`
+     - `git.mcpeakdev.com/mcpeakdev/nychthemeron-docs:latest`
+
+## Out of scope
+
+- No changes to the existing `build` or `publish` (npm) jobs beyond what's
+  already in place.
+- No SPA routing / custom nginx config — Storybook's static output is
+  served as-is.

+# Remove reka-ui dependency
+
+## Context
+
+The library recently finished migrating off PrimeVue onto a shadcn-vue-style
+component set (`ff02f7e chore: remove PrimeVue and the ThemeEngine, migration
+complete`). That migration adopted `reka-ui` (the Vue port of Radix
+primitives) as the headless behavior layer under `Button`, `Checkbox`,
+`Switch`, `RadioGroup`, `Dialog`, and `Select`. `reka-ui` is currently a
+`peerDependency` of `@nychthemeron/library`, meaning every consumer of the
+library has to install it too.
+
+Goal: drop `reka-ui` entirely — fewer dependencies for the library and its
+consumers, no external headless-UI surface to track for breaking changes —
+by hand-rolling the behavior each component needs directly in this repo.
+
+This is an internal implementation swap. No component's public props, emits,
+slots, or CSS classes change; Storybook stories in `packages/playground`
+should work unmodified against the new implementations.
+
+## Scope
+
+Files currently importing from `reka-ui` (24 total, `packages/library/src/components/ui/`):
+
+- `button/Button.vue`
+- `checkbox/Checkbox.vue`
+- `switch/Switch.vue`
+- `radio-group/RadioGroup.vue`, `radio-group/RadioGroupItem.vue`
+- `dialog/*.vue` (10 files: Dialog, DialogTrigger, DialogContent,
+  DialogOverlay, DialogClose, DialogTitle, DialogDescription, DialogFooter,
+  DialogScrollContent, plus the already-presentational DialogHeader which
+  doesn't import reka-ui but lives in the same family)
+- `select/*.vue` (11 files: Select, SelectTrigger, SelectValue,
+  SelectContent, SelectItem, SelectItemText, SelectLabel, SelectGroup,
+  SelectSeparator, SelectScrollUpButton, SelectScrollDownButton)
+
+## Key decisions
+
+**Dialog is built as a fully custom `div` + `Teleport`, not on the native
+`<dialog>` element.** Native `<dialog>` would give focus-trap/ESC/top-layer
+behavior for free, but its `close()` removes the element from the render
+tree immediately, which fights the fade/zoom exit animation the current
+design already has (`data-closed:animate-out data-closed:fade-out-0
+data-closed:zoom-out-95`). A `<Transition>`-driven custom implementation
+lets the leave animation play out naturally before unmount.
+
+**Select is a fully custom listbox, not a native `<select>`.** The current
+design has a styled popover (rounded corners, shadow, slide/fade animation,
+scroll-up/down buttons) that native `<select>` cannot reproduce — its
+dropdown is unstyleable OS chrome in every browser. Given the existing
+Storybook stories only exercise flat item lists (no search/multi-select),
+a hand-rolled listbox with manual keyboard nav and simple fixed-position
+placement is sufficient and preserves the current visual design exactly.
+
+**No positioning library.** Select's popover placement is computed manually
+via `getBoundingClientRect()` (flip above the trigger when there's
+insufficient room below, recalculate on scroll/resize while open) rather
+than pulling in `@floating-ui/dom` or using CSS anchor positioning (the
+latter is Chrome/Edge-only today, not viable for full browser support).
+
+## Shared internal primitives
+
+New composables/utilities under `packages/library/src/lib/` (or similar),
+used across the affected components instead of one large headless library:
+
+- **`Slot` (asChild helper)** — clones the single child VNode and merges
+  the parent's props/listeners onto it. Needed for `Button`'s `asChild`,
+  `DialogTrigger as-child`, `DialogClose as-child`, `SelectIcon as-child`.
+  This is the one piece of VNode-cloning plumbing kept in the codebase.
+- **Portal** — Vue's built-in `<Teleport to="body">` directly; no wrapper
+  component needed.
+- **`useFocusTrap`** — on activation, moves focus into a container, cycles
+  Tab/Shift+Tab within its focusable descendants, restores focus to the
+  previously-focused element on deactivation. Used by Dialog and Select.
+- **`useDismissableLayer`** — closes on Escape keydown and on
+  click/pointerdown outside a given container. Used by Dialog (overlay
+  click + Escape) and Select (outside click + Escape).
+- **`useRovingFocus`** — arrow-key navigation across a set of items with a
+  single tab stop (only the active item is in the tab order). Used by
+  `RadioGroup`.
+- **`usePopoverPosition`** — computes `fixed` top/left for a floating
+  element relative to a trigger's `getBoundingClientRect()`, flips
+  above/below based on available viewport space, recalculates on
+  scroll/resize while open. Used by Select's listbox.
+- **Scroll lock** — reuse `@vueuse/core`'s `useScrollLock` (already a
+  dependency) rather than writing a new composable. Applied to `<body>`
+  while Dialog or Select is open.
+
+## Per-component plan
+
+- **Button** — replace `Primitive` with `<component :is="as">` (default
+  `'button'`), using the new `Slot` helper when `asChild` is true.
+
+- **Checkbox / Switch** — reka's `CheckboxRoot`/`SwitchRoot` currently
+  render as a `<button role="checkbox|switch">` with `aria-checked` and a
+  `data-checked`/`data-unchecked` attribute that the existing Tailwind
+  classes key off of (e.g. `data-checked:bg-primary`). Reimplement that
+  directly: a `<button type="button">` managing `v-model`, setting
+  `aria-checked`, `data-checked`/`data-unchecked`, forwarding
+  `disabled`/`aria-invalid`, toggling on click (Space/Enter activation is
+  native `<button>` behavior, no extra handling needed). Markup and classes
+  stay identical — no visual change.
+
+- **RadioGroup / RadioGroupItem** — `role="radiogroup"` wrapper +
+  `role="radio"` buttons using `useRovingFocus` for arrow-key movement and
+  single-tab-stop behavior; `v-model` on the group for the selected value.
+
+- **Dialog family** — `Dialog` (root) holds `open` state via
+  `provide`/`inject`, matching the current `v-model:open` API.
+  `DialogTrigger` toggles it (`asChild` supported via `Slot`).
+  `DialogContent` teleports to `body`, renders overlay + panel, applies
+  `useFocusTrap` + `useDismissableLayer` + scroll lock while open, and
+  drives the fade/zoom animation with `<Transition>`. `DialogTitle` /
+  `DialogDescription` generate and wire `aria-labelledby` /
+  `aria-describedby` back onto the content. `DialogOverlay`,
+  `DialogHeader`, `DialogFooter`, `DialogClose`, `DialogScrollContent`
+  are thin/presentational already or need only a trivial context hookup.
+
+- **Select family** — `Select` (root) holds `open`/`modelValue` via
+  `provide`/`inject`. `SelectTrigger` is a `role="combobox"
+  aria-expanded` button. `SelectContent` teleports, positions itself with
+  `usePopoverPosition`, traps focus, and owns keyboard handling: Up/Down
+  move a highlighted item, Enter/Space selects, Escape/outside-click
+  closes, typeahead jumps to the first item matching typed characters.
+  `SelectItem` / `SelectItemText` / `SelectLabel` / `SelectGroup` /
+  `SelectSeparator` read highlighted/selected state from the injected
+  context. `SelectScrollUpButton` / `SelectScrollDownButton` become simple
+  "is the viewport scrolled away from the top/bottom" indicators driven by
+  a scroll listener, rather than reka's internal viewport machinery.
+
+This family carries the most real accessibility surface (the listbox
+keyboard pattern), so beyond unit tests it needs a manual pass in
+Storybook against the existing stories: keyboard nav, focus return, and
+Escape/outside-click behavior.
+
+## Package/build changes
+
+- `packages/library/package.json`: remove `reka-ui` from
+  `peerDependencies`.
+- `packages/library/vite.config.ts`: remove `reka-ui` from the Rollup
+  `external`/`output.globals` config.
+- No new dependencies added.
+
+## Testing
+
+- Vitest unit tests (`@vue/test-utils` is an existing but currently-unused
+  devDependency) for the composables with real logic and failure modes:
+  `useFocusTrap`, `useRovingFocus`, `useDismissableLayer`, and Select's
+  keyboard/typeahead handling.
+- Presentational components remain covered by the existing Storybook
+  stories rather than new component-level tests.
+- Manual verification: exercise every existing Storybook story for
+  Button/Checkbox/Switch/RadioGroup/Dialog/Select in a browser (headless
+  Chromium per the existing Storybook screenshot setup), checking keyboard
+  navigation, focus return, and Escape/outside-click behavior by hand, not
+  just visual diffing.
+
+## Non-goals
+
+- No visual/CSS changes to any component.
+- No new features (multi-select, search/combobox, non-modal dialogs, etc.)
+  beyond what the current reka-ui-backed components already support and
+  the existing stories exercise.
+- No changes to consumers outside this repo's `packages/playground`; the
+  public component API is preserved exactly.
