## Features

- Five labelled slots — Home, Search, Files, Alerts, Profile — each a real 24x24 Tabler icon above a micro label
- A translucent bar with a 12px backdrop blur and a saturating filter floats on its own tinted wash panel, so the glass has something to refract
- A frosted pane slides behind the active slot on a 0.45s curve, edged with an inset light ring
- The wash is a two-point radial mix of the selection fill and the accent over the system scrim, dark enough in both themes for the light ink the glass carries
- The wash frame steps its corner up from the glass radius by the inset, so the two arcs stay concentric on every system
- Roving `tabindex` with Arrow/Home/End key navigation and `aria-current="page"` on the active link
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Navigation landmark** — `<nav aria-label="Primary">` wraps the slot list
- **Current slot** — `aria-current="page"` on the active link
- **Decorative icons** — All SVGs marked `aria-hidden="true"` and `focusable="false"`
- **Focus indicators** — `:focus-visible` outlines on every link and control, never composed into a `box-shadow` list
- **Keyboard navigation** — Roving tabindex with Arrow, Home and End keys
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations

## Keyboard shortcuts

- `Tab` — Move focus into and out of the slot list
- `ArrowLeft` — Move to the previous slot
- `ArrowRight` — Move to the next slot
- `Home` — Move to the first slot
- `End` — Move to the last slot
