- answer-modal: __content (scroll area), __submit (footer)
- notifications-bridge: skip comment (bridge, non-rendering wrapper)
- notifications-realtime-mount: skip comment (returns null)
- notifications-sheet: __header, __items (questions list)
- push-toggle: __switch (button), __label (button text) on subscribed/unsubscribed states
