## Features

- Two-column split with mirrored asymmetric sub-grids — the wide tile sits bottom-left and top-right for diagonal visual weight
- Six theme-named tiles (resilience, growth, vision, engagement, insight, focus) — each carries equal structural weight
- Skeleton wireframe placeholders: bars, blocks, ruled chart panels, avatar dots, and pills
- Responsive breakpoints at 480px and 768px with grid reconfiguration
- Dark/light theme toggle 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="Split 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
