## Features

- Paired dots translate across each other to form a double helix
- Connecting rungs drawn with a thin gradient-tinted line
- GPU-friendly — animates `transform` and `opacity` only
- Design-system agnostic — dot colors resolve from gradient 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 wash layer marked `aria-hidden="true"`
