/**
 * A modal window centred over the page. Focus moves into it when it opens,
 * stays trapped inside, and returns to the trigger when it closes; Escape and
 * a click on the overlay close it, and the page behind it does not scroll.
 * Screen readers announce it as a dialog named by `DialogTitle` and described
 * by `DialogDescription`. With reduced motion it appears without fading or
 * zooming.
 *
 * @example
 * <Dialog>
 *   <DialogTrigger asChild>
 *     <Button>Edit profile</Button>
 *   </DialogTrigger>
 *   <DialogContent>
 *     <DialogHeader>
 *       <DialogTitle>Edit profile</DialogTitle>
 *       <DialogDescription>Changes are saved when you press Save.</DialogDescription>
 *     </DialogHeader>
 *     <DialogFooter>
 *       <DialogClose asChild>
 *         <Button variant="outline">Cancel</Button>
 *       </DialogClose>
 *       <Button>Save</Button>
 *     </DialogFooter>
 *   </DialogContent>
 * </Dialog>
