## Features

- A single ring with four border colors from the gradient tokens
- Two solid sides and two faded sides create a dual-tone spin
- GPU-friendly — animates `transform: rotate` only
- Design-system agnostic — border colors resolve from tokens
- 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 vignette layer marked `aria-hidden="true"`
