One-line: confirm something you cannot undo — narrower than Dialog (416px), no dismiss X, no backdrop click-out.

```jsx
<AlertDialog>
  <AlertDialogTrigger><Button variant="destructive-outline">Delete event type</Button></AlertDialogTrigger>
  <AlertDialogPopup>
    <AlertDialogHeader><AlertDialogTitle>Delete “30 min meeting”?</AlertDialogTitle><AlertDialogDescription>Existing bookings stay, but the link stops working immediately.</AlertDialogDescription></AlertDialogHeader>
    <AlertDialogFooter><AlertDialogClose><Button variant="ghost">Keep it</Button></AlertDialogClose><Button variant="destructive">Delete</Button></AlertDialogFooter>
  </AlertDialogPopup>
</AlertDialog>
```

Name the consequence in the title, not "Are you sure?".
