## Features

- Inset LED window with a 6–24 bar neon spectrum, thin bars, and a scanline texture drawn from tokens
- Three keyframe motion variants assigned cyclically with per-bar duration and delay jitter so the wave reads like music
- Solid backlit play key that flips between pause and play glyphs with the transport state
- Live deck readout: a pulsing LED dot and an uppercase Live / Standby status
- Three speed presets (0.5x, 1x, 2x) that retune the animation duration
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Status region** — `aria-live="polite"` paragraph announces Live / Standby changes
- **Play toggle** — `<button>` with `aria-pressed` and dynamic `aria-label` (Play/Pause)
- **Preset and speed tabs** — Mutually exclusive `aria-selected` tabs inside labeled `role="tablist"` groups, with roving `tabindex` and arrow-key navigation
- **Bar count** — `aria-live` count with a descriptive `aria-label` announcing the number of waves
- **Keyboard activation** — All actions use native buttons that respond to Enter and Space
- **Focus indicators** — `:focus-visible` with `--ring` outline on all interactive elements
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations and transitions

## Keyboard shortcuts

- `Enter` — Activate the focused button
- `Space` — Activate the focused button
- `Tab` — Move focus between interactive elements
