Page Layout (3 components):

Technical Changes

• All components exported from src/index.ts
• Showcase pages with examples for each component
• Navigation and routing updated
• Fixed CalendarHeading/RangeCalendarHeading slot bindings
• Fixed Sonner export naming conflict (renamed to Sonner)
• Added @types/d3-dispatch override for TypeScript compatibility
• Added skipLibCheck: true to tsconfig.json

Test Coverage

• Fixed textarea tests (removed tests for non-existent charLimit feature)
• Added smoke tests for all 30 components that were missing tests
• All 64 components now have test coverage (88 tests total)

Build Improvements

• Fixed build order: vite build runs before type-check so emptyOutDir: true works correctly
• Added dist/index-*.js to gitignore (docs app bundle artifact)
• Cleaned up stale type definitions from deleted components

Not Available in Registry

Some components from the shadcn-vue docs sidebar are not yet available in the CLI registry:

• native-select, typography, data-table

Anything the reviewer needs to know

• No breaking changes - all additions are new exports
• Build artifacts are now properly cleaned between builds
• All components have smoke test coverage

Test plan

• npm run build passes
• npm run lint passes
• npm run test passes (88 tests)
• Verify each component renders correctly in the docs app
• Test interactive components (Calendar, Toggle, etc.)

Bug: The Sidebar component unconditionally calls useSidebar(), which will throw an error if not wrapped in a SidebarProvider, even when collapsible="none" and the context is not used.
_{Severity: HIGH}

Suggested Fix

The call to useSidebar() should be made conditional. It should only be executed when the collapsible prop is not equal to 'none', as the returned values are not used in that case. This will allow the component to be used in its static form without requiring a provider.

Location: src/components/sidebar/Sidebar.vue#L26

Potential issue: The `Sidebar` component calls the `useSidebar()` hook unconditionally
on line 26. This hook requires a `SidebarProvider` to be present in the parent component
tree and will throw an injection error if it's missing. However, when the component is
used with the prop `collapsible="none"`, it renders a static version that does not use
any of the values from the context. Therefore, any attempt to use `<Sidebar
collapsible="none">` without a `SidebarProvider` will cause the application to crash,
even though it should logically work as a standalone component in this configuration.
