…folding Spec for issue #83 Phase 1: Storybook 10 initialization, configuration, and story scaffolding for all 100 components. Includes spike gate for SB10+React 19 compatibility, tiered next/* functional mocks, shared Vite config extraction, and compound component story refinement.

…e check - Add @storybook/test-runner, @storybook/addon-designs, @storybook/addon-mcp - Add check-story-coverage.ts CI script ensuring 100% story coverage - Promote story coverage enforcement to Must Have (AC-10) - Expand scope to 14 items (0-12 + 8b)
- Configure .storybook/main.ts with React-Vite, a11y, themes, designs, MCP addons - Configure .storybook/preview.ts with dark mode toggle via withThemeByClassName - Create next-stubs.ts for Next.js component mocking (Link, Image, navigation) - Create story generator script with CVA variant extraction for Controls - Create story coverage check script (check:stories) - Generate stories for all 99 components with automatic argTypes - Manually refine 6 compound stories (dialog, sheet, dropdown, sidebar, toast, mdx-content) - Add Storybook scripts to package.json + turbo.json pipeline - Exclude stories from tsup build and tsc typecheck - Add storybook-static/ to .gitignore - Update ESLint config to ignore storybook build output
- Create StorybookEmbed client component (iframe wrapper with loading state) - Create sync-from-storybook.ts script (maps story IDs to registry components) - Generate component-metadata.json from Storybook index.json + registry.json - Refactor [slug]/page.tsx to use StorybookEmbed + synced metadata - Refactor components/page.tsx to use metadata cards instead of previews - Delete ComponentPreview switch statement (1,714 LOC) - Delete 34 MDX files (header.mdx + example.mdx) - Add "View in Storybook" links with story variant badges - shadcn /r/*.json API unchanged Stories are now the single source of truth for component visualization.
Two bugs fixed:
1. Storybook stories never rendered (infinite spinner) because
`addonThemes.withThemeByClassName` was tree-shaken from the
default export during Rollup bundling. Switch to named import
`{ withThemeByClassName }` which survives tree-shaking.
2. StorybookEmbed showed "Loading preview..." forever because the
iframe `onLoad` event fired before React hydration attached the
handler. Fix: lazy-load iframe src via useEffect (client-side
only) so onLoad always fires after handler is attached. Use
opacity instead of display:none so iframe renders while loading.
Organize 99 story files into 8 categories (Content, Core, Data, Form, Learning, Navigation, Overlay, Utility) based on registry.json metadata. Update generate-stories.ts to read categories for future generation. Re-sync component-metadata.json with new story IDs.
…nner addons - Generate MDX documentation for all 99 components with install commands, imports, props tables, variant galleries, and story canvases - Add generate-docs.ts script for MDX doc generation - Add @storybook/addon-docs for MDX rendering - Add @github-ui/storybook-addon-performance-panel for perf monitoring - Add @chromatic-com/storybook for visual testing - Include *.mdx in Storybook stories glob
SB10 requires addon-docs in both main.ts (server/MDX plugin) and preview.ts addons array (DocsRenderer parameter). Missing the preview registration caused docs pages to render as white screens. Also adds docs-overrides.css to restore typography after Tailwind Preflight resets default styles in the docs iframe.
Register addonPerformance() in preview.ts addons array so the performance panel decorator applies globally without per-story config.
…, and compound API support Rewrite generate-docs.ts for comprehensive documentation: - Deep prop extraction: arrays, callbacks, ReactNode, unions, objects - Inline type definitions with code blocks and field tables - Compound component API reference (Accordion.Item, FAQ.Item, etc.) - Usage examples: array props, compound patterns, simple components - Canvas sourceState="shown" for code preview on all stories - Deduplicate sub-components attached via dot notation
…ents - 37 unit tests (vitest + testing-library) covering simple components - 96 Playwright CT visual tests with baseline snapshots - 127 visual snapshot baselines for regression detection - Removed mdx-content visual test (async component, unmountable in CT)

changed the title
- Add stories and visual tests to eslint ignores (excluded from tsconfig) - Fix Playwright install: use pnpm exec instead of npx in monorepo - Auto-fix quote style in generated visual/test files - Add test-runner-jest.config.ts to tsconfig include
- Remove .snapshots/ from .gitignore so visual regression works in CI - Commit 127 baseline screenshots for Playwright CT visual tests - Fix http-server startup: install globally + wait-for-ready loop
… blocking - Move test-runner config to .storybook/test-runner.js (standard location) - test-storybook job: continue-on-error until jest/ESM conflict resolved - visual-regression job: now blocking (snapshots committed to repo) - Remove old test-runner-jest.config.ts from package root
…cking Snapshots generated locally differ from CI due to OS font rendering. Added 5% maxDiffPixelRatio tolerance. Visual regression is non-blocking until snapshots are regenerated in CI environment.
…flict Jest auto-discovers files in __tests__/ directories. The storybook test-runner uses Jest internally and was finding src/__tests__/setup.ts as a test file, failing on ESM import syntax. Moved to src/test-setup.ts.
package.json has "type": "module" so .js files are treated as ESM. Convert module.exports to export default in test-runner configs. Clean up stale test-runner-jest.config.ts references from eslint ignores and tsconfig include.
The test-runner-jest.config.js was only needed to ignore __tests__/ which no longer exists. Removing eliminates the require() ESM error since Jest can't require() an ESM .js file.
- step-by-step: provide Step children with title props - tooltip: add TooltipProvider decorator - resizable: use ResizablePanelGroup with panels and handle - theme-toggle: provide required dict prop, add next-themes stub - navbar-saas: add SidebarProvider decorator - toggle-group: add required type prop and ToggleGroupItem children
