## Features

- Wireframe → fill reveal: each shape starts as a 1px outline, then a filled overlay crossfades in and out on an infinite loop (opacity only, no layout shift)
- Staggered cascade — the fill sweeps top to bottom, shape by shape, via per-shape animation delays
- Article-card layout — tall image block, title line, three body lines, and a footer byline with a pill
- Click or press Enter/Space to replay the load-in animation
- All colors, spacing, and radii driven by design-system tokens
- Dark/light mode via the `body.dark` class
- Prefers-reduced-motion support
- Accessible: `role=status`, `aria-busy`, screen-reader loading label
