 "title": "Storefront accessibility pass: one product page with four planted issues, then the clean sample shop",
 "about": "A product page from Harbor & Pine, a made-up shop, pasted as HTML with its images inline (the browser has no network for pasted pages). Four issues are planted: the packshot's alt says the can is purple (it is orange), Add to cart is a div the keyboard cannot reach, the quantity field has no label, and a banner offer exists only inside the image. The audit must find the rule-engine issue, the keyboard blocker (as P1) and the two model-judged ones, attach a receipt to every model call, and sign a record that verifies. Then the clean version of the sample shop, without the model, must come back with nothing found.",
