Redesign switch

What this tests. The same fifty products in two layouts with every class renamed, plus a crossed-out price and a shipping charge to lure the wrong number.

Write your selectors against layout v1, then run them unchanged against layout v2. Version 2 renames every class, swaps paragraphs for spans and moves the title into a different heading. It's the overnight redesign that breaks a scraper on a Tuesday. Both versions show a crossed-out "was" price and a shipping charge right beside the real price, so a selector that grabs "the first number that looks like money" gets it wrong in both.

Which layout you get depends only on the path. Nothing rotates, nothing is random.
