The socket had no recovery path: a mid-game drop left the table showing stale state with no indication, and plays were silently swallowed by the dead channel. Surface the server close code from ws::connect and add a reconnect driver in the game page: transient losses retry with exponential backoff (capped, then a manual Retry), while deliberate closes (session expired, game gone) stop retrying. Reconnects are free resyncs because the server pushes a full state snapshot on connect. Also gate card clicks while disconnected, show a connection banner, and drop the ticking interval and pending retries on unmount.
