 * host would drop the React context of the declaration site; `Modal` keeps its
 * children in the same React tree, so `Popover.Popup` still sees the root store.
 *
 * `statusBarTranslucent` matters for positioning: it makes the modal's origin
 * the top of the screen, which is the coordinate space `useAnchorPositioning`
 * resolves the anchor into.
