feat(headless): add package foundation with Dialog primitive
d9993d7
Introduces the @clerk/headless package — a zero-style React component
library providing accessible headless UI primitives. This first PR
establishes the core infrastructure and patterns:
- Package scaffold: Vite build, Vitest browser tests (Chromium), TypeScript config
- Core utils: renderElement (polymorphic rendering with render prop support),
mergeProps (event handler chaining, style/className merging)
- Hooks: useControllableState, useTransitionStatus, useAnimationsFinished, useTransition
- First primitive: Dialog (modal with focus trapping, scroll lock, portal support)

Superseded by #8790, which consolidates the remaining headless primitive stack (Tabs → Collapsible) into a single PR for one review pass. Closing in favor of that.

Superseded by #8790, which consolidates the remaining headless primitive stack (Tabs → Collapsible) into a single PR for one review pass. Closing in favor of that.

feat(headless): add package foundation with Dialog primitive
d9993d7
Introduces the @clerk/headless package — a zero-style React component
library providing accessible headless UI primitives. This first PR
establishes the core infrastructure and patterns:
- Package scaffold: Vite build, Vitest browser tests (Chromium), TypeScript config
- Core utils: renderElement (polymorphic rendering with render prop support),
mergeProps (event handler chaining, style/className merging)
- Hooks: useControllableState, useTransitionStatus, useAnimationsFinished, useTransition
- First primitive: Dialog (modal with focus trapping, scroll lock, portal support)

feat(headless): add package foundation with Dialog primitive
d9993d7
Introduces the @clerk/headless package — a zero-style React component
library providing accessible headless UI primitives. This first PR
establishes the core infrastructure and patterns:
- Package scaffold: Vite build, Vitest browser tests (Chromium), TypeScript config
- Core utils: renderElement (polymorphic rendering with render prop support),
mergeProps (event handler chaining, style/className merging)
- Hooks: useControllableState, useTransitionStatus, useAnimationsFinished, useTransition
- First primitive: Dialog (modal with focus trapping, scroll lock, portal support)

Superseded by #8790, which consolidates the remaining headless primitive stack (Tabs → Collapsible) into a single PR for one review pass. Closing in favor of that.
