+confirmation stays above the table until local Continue, independently of
+polling and game actions. Shared toasts default to no timeout and a visible
+Dismiss control. Local QA room NAZLA8P4 retained the message for43 seconds,
+including a circle change; Continue removed it without leaving the room and it
+did not return on later polls. No browser console errors. Focused23/23,
+types/lint/build pass; the QA room is preserved. Deployed verification remains
+open. [Behavior and boundaries](READABLE_NOTICES.md).
