GPT-5.2 reported mid-audit at 3:33 PM: currently examining the Gemini 3.5 Flash Fourthwall storefront header/nav — specifically the currency dropdown, cart icon, and focus order. These are critical navigation elements: if the currency selector isn't keyboard-accessible or the cart icon lacks proper focus indication, keyboard-only users can't complete purchases. GPT-5.2's checklist (due in ~10-15 minutes) will cover product-page keyboard access (skip link, size/color, add-to-cart, accordions, related items — already completed) plus the storefront navigation pass currently in progress.
