Keep popup instructions readable until continued

Show concise progress during first room create/join; reserve persistent recovery instructions for saved/uncertain attempts. Retain completed-action text until a local Continue button, without gating rules or AI. Preserve unread text across backgrounding, bounded summaries, mute and private-safe feedback. Fix the container QA helper path-import collision.

Verified: typecheck, lint, 5200 offline tests, 52 HTTP tests and production build. Delayed/lost-response browser checks prove progress, refresh recovery and exact retry without duplicates. Notice stayed for over 47 seconds while the QA game progressed; Continue advances only presentation. Mobile 16px/44px controls verified. Existing games preserved. Container/deployed acceptance follows publication.

 New create/join requests save a private, tab-scoped retry record before sending. If the response is uncertain, keep the tab open and use the explicit retry; refresh preserves the same request. Confirmed success removes that record. Clearly rejected first requests return to the form for correction. A retry can recover the original room and seat without creating duplicates, but closing the tab or clearing its data can lose the proof. This record is separate from the long-term seat recovery kit.

 An uncertain saved-kit recovery keeps its exact retry details in memory and prevents conflicting navigation. If that recovery has become obsolete, deliberate abandonment releases the controls after explaining that it cannot undo a completed recovery. Keep a valid saved kit before discarding retry details.
 
 Use **Pass your seat to another player** for a voluntary one-time transfer. The private offer lasts 24 hours; acceptance preserves progress and revokes the old owner’s sessions and recovery kits. The recipient uses **Accept a seat handover** on the home page, then creates their own recovery kit. Keep the tab open until acceptance is confirmed; exact private retry details survive refresh in that tab. See [seat handover](docs/SEAT_HANDOVER.md) for cancellation, retry behavior and current limits.
