/**
 * AlertDialog — blocking confirm dialog backed by Radix `AlertDialog`.
 *
 * Use for **short, blocking** confirms where the user MUST acknowledge before
 * the surface behind can be interacted with again — destructive deletes,
 * irreversible status changes, legal acknowledgements, etc. (See
 * `.cursor/rules/exxat-drawer-vs-dialog.mdc` for the drawer-vs-dialog rule.)
 *
 * Differences from the regular `Dialog` primitive:
 *  - Radix sets `role="alertdialog"` automatically — screen readers
 *    announce the title + description immediately.
 *  - Cannot be dismissed by overlay click or `Esc` (only the explicit
 *    `AlertDialogCancel` / `AlertDialogAction` buttons close it).
 *  - Ships an `Action` (primary destructive / commit) + `Cancel`
 *    (secondary dismiss) pair that map to `Button` variants without
 *    additional wiring.
 *
 * Accessibility:
 *  - WCAG 4.1.2 — `AlertDialogTitle` is REQUIRED. Hide it visually with
 *    `sr-only` if the design omits the heading, but never omit the element.
 *  - WCAG 2.1.2 — focus is trapped inside the dialog while open (Radix).
 *  - WCAG 3.3.4 — pair destructive actions with explicit, named verbs
 *    ("Delete site" rather than "OK").
