## Features

- Five dots scale up and down with a staggered delay
- Dots tinted across the signature gradient via `color-mix`
- GPU-friendly — animates `transform` and `opacity` only
- Design-system agnostic — colors 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 dot-grid layer marked `aria-hidden="true"`
