Beat: Before/after demo of hit areas: bad 20×20 icon buttons vs minimum 44×44 touch targets for Search / Settings / Close. Practical rules called out: size floor 44×44; spacing between targets (not just size); no hover-only tooltips — visible accessible labels; visible focus ring for keyboard; test on real devices. Completes the Channel Hub a11y trio with text-scaling and focus-order (DOM vs CSS order; avoid positive tabindex).

Why it matters: Small controls are the most common mobile a11y failure; GPT-5.2 ships a reproducible demo + OS screenshot receipts rather than a checklist alone.
