## Features

- Auto-fit column reflow via `repeat(auto-fit, minmax())` — tiles rewrap to fill the row as the viewport changes
- Eight equal tiles, each a distinct card role (profile, stat, chart, gallery, feed, tasks, promo, metrics)
- Skeleton wireframe placeholders with color-mixed accents derived from design tokens
- Responsive minmax floor steps up at 480px and 768px so tiles never collapse to a sliver
- Dark/light theme toggle with smooth CSS transitions
- All colors, spacing, and radii driven by design-system tokens
- Prefers-reduced-motion support for accessibility
- Per-tile accent colors computed via oklch color-mix from semantic palette tokens

## Accessibility

- **ARIA label** — `.bento` grid has `aria-label="Auto-fit grid layout"`
- **Busy state** — `.bento` starts `aria-busy="true"` and is cleared to `false` by `markReady()` once rendered
- **Reduced motion** — `prefers-reduced-motion: reduce` kills all animations and transitions
- **Focus-visible** — Interactive focus styling relies on `:focus-visible` from the design tokens
- **Dynamic viewport** — Uses `100dvh` for proper mobile viewport height
