## Features

- Trigger button that toggles an anchored attention popover open and closed
- 5x5 query/key attention matrix — row tokens attend to column tokens, so the bright diagonal reads as self-attention
- Token axis labels on both axes: rotated key tokens across the top, query tokens down the left, aligned to the heatmap tracks
- The focused `deep` token is emphasized typographically on both axes without label background fills
- Hover a heatmap cell to spotlight it and read its `query → key · weight` tooltip
- Legend row with an axis hint ("rows attend to columns") and a 0→1 weight scale
- Live model status footer with a pulsing activity dot
- Click outside the popover or press Escape to dismiss it
- Responsive down to 240px
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Dialog role** — The popover uses `role="dialog"` with an `aria-label`
- **Trigger semantics** — The trigger has `aria-haspopup`, `aria-expanded` and `aria-controls`
- **Informative heatmap** — The labeled matrix is exposed as `role="img"` with an `aria-label` naming the tokens, the query/key axes, and the diagonal self-attention pattern
- **Cell tooltips** — Each cell carries a `title` of the form `query → key · weight` for sighted hover reading
- **Decorative visuals** — The legend and arrow are `aria-hidden`
- **Focus indicators** — `:focus-visible` with `--ring` outline on all interactive elements
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations

## Keyboard shortcuts

- `Escape` — Close the popover and restore focus to the trigger
