## Features

- Nine named cells (left-top, main-top-left, main-top-right, right-top, main, left-bottom, main-bottom-left, main-bottom-right, right-bottom)
- Corner-and-center emphasis: four corner accents wrap a large 2×2 central hero cell on desktop
- Each cell carries its own hue — in a bento the cell's identity is the message
- Skeleton wireframe placeholders: bars, blocks, ruled chart panels, avatar dots, and pills
- Three-breakpoint reflow at 480px and 768px with full grid reconfiguration
- CSS-only dark mode (`body.dark`) with smooth CSS transitions
- All colors, spacing, and radii driven by design-system tokens
- Prefers-reduced-motion support for accessibility
- Cell accent colors computed via oklch color-mix from semantic palette tokens

## Accessibility

- **ARIA label** — `.bento` grid has `aria-label="Nine-cell bento 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
