## Features

- Semantic `<nav aria-label="Breadcrumb">` wrapping an ordered list
- Middle crumbs collapse behind an ellipsis button with `aria-expanded` and `aria-controls`
- Clicking the ellipsis reveals hidden levels immediately in accent ink without width, position, opacity, or scale animation
- Keyboard accessible — the ellipsis is a native button activated by Enter and Space
- Current page rendered as non-link text with `aria-current="page"`
- Leading home icon and chevron separators from real 24x24 Tabler icons
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Navigation landmark** — `<nav aria-label="Breadcrumb">` wraps the ordered list
- **Expandable control** — Ellipsis button uses `aria-expanded` and `aria-controls`
- **Current page** — `aria-current="page"` on non-link current crumb
- **Decorative separators** — Chevrons marked `aria-hidden="true"`
- **Focus indicators** — `:focus-visible` with `--ring` outline on links and the ellipsis button
- **Reduced motion** — Reveal geometry is motion-free; `prefers-reduced-motion: reduce` shortens remaining paint transitions

## Keyboard shortcuts

- `Tab` — Move focus between crumbs and the ellipsis
- `Enter` — Activate the focused ellipsis, crumb link
- `Space` — Activate the focused ellipsis
