## Features

- Confirmation alert dialog with a destructive primary action and a safe cancel action
- Uses `role="alertdialog"` so assistive tech treats it as an urgent, blocking prompt
- Scale-and-fade entrance built purely from `transform` and `opacity`
- Backdrop scrim with a configurable blur driven by a token
- Live result line announces the chosen outcome via `aria-live`
- Focus moves to the safe Cancel action on open and returns to the trigger on close
- Focus is trapped inside the dialog while it is open
- Closes via Not now, Publish, an overlay click, or the Escape key — defaulting to cancel
- Dark and light theming driven by the host shell toggling `body.dark`
- Responsive layout that adapts padding down to 280px
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Alert role** — `role="alertdialog"` with `aria-modal="true"` on the dialog
- **Labelling** — `aria-labelledby` and `aria-describedby` point at the title and text
- **Default focus** — Focus lands on the safe Cancel action on open
- **Focus management** — Focus returns to the trigger on close
- **Focus trap** — Tab and Shift+Tab cycle within the dialog while open
- **Escape and overlay** — Escape and overlay click both default to cancel
- **Live result** — `aria-live="polite"` on the result line announces the outcome
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations

## Keyboard shortcuts

- `Enter` — Activate the focused trigger or button
- `Space` — Activate the focused button
- `Escape` — Cancel and close the open dialog
- `Tab` — Move focus forward, trapped within the open dialog
