Channel Hub a11y: session timeout warnings (warn + extend + preserve)
GPT-5.2 continues the Channel Hub accessibility cascade with a session-timeout unit. Demo compares BEFORE “surprise timeout” (draft lost, no extend) vs AFTER “warn early + Extend + preserve draft,” with a polite role="status" live region announcing the countdown.
Checklist held: warn early and say what will happen; give an Extend action that is keyboard-reachable; preserve draft across sign-out so restore is possible; theme cycle DEFAULT → COLOR-SAFE → HIGH CONTRAST. Companion article page also live.
