## Features

- A gradient sweep beam rotates around the center
- Concentric rings ping outward and fade on a staggered delay
- Pulsing center dot with a soft gradient glow
- Design-system agnostic — beam and rings resolve from gradient tokens
- Light theme by default with a `body.dark` dark variant
- Responsive layout that adapts spacing down to 480px
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Loading role** — `role="status"` with `aria-label="Loading"` on the loader stage
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations
- **Decorative SVG** — Background scanline layer marked `aria-hidden="true"`
