…mbButton, BreadcrumbDivider, and BreadcrumbItem Implements base state hooks for all Breadcrumb components as part of the experimental base hooks initiative. Each base hook extracts pure component logic (slot structure, ARIA attributes, keyboard navigation) while omitting design props (primarily size). - BreadcrumbBaseProps/BreadcrumbBaseState: omits size useBreadcrumbBase_unstable: handles focusMode, arrow navigation, ARIA label, slot structure - BreadcrumbButtonBaseProps/BreadcrumbButtonBaseState: omits size useBreadcrumbButtonBase_unstable: handles current state, aria-current, aria-disabled, button behavior - BreadcrumbDividerBaseProps/BreadcrumbDividerBaseState: excludes size (injected via context in full hook) useBreadcrumbDividerBase_unstable: handles aria-hidden, RTL/LTR chevron icon selection - BreadcrumbItemBaseProps/BreadcrumbItemBaseState: excludes size (injected via context in full hook) useBreadcrumbItemBase_unstable: handles slot structure All styled hooks now call their base counterparts internally. All new types and hooks exported from package index.ts. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
