    "boundary": "The test is “one product, all of its attributes, chosen and added to the cart on the page”. It is not a landing page: a landing page tells only what one conversion needs and orders it for persuasion, while a product page answers every pre-purchase question and users skim it in their own order. Nor is it master–detail: master–detail keeps the selectable list and the detail on the same screen, while a product page is usually a separate page reached from a product list that does not stay in view. Product lists and comparison tables are for choosing among several products; the product page is for confirming one. Prices, stock and reviews on the page must be genuine: hiding unavoidable costs, inventing scarcity or faking reviews are anti-patterns and fall outside this entry.",
