A product page has one job

A product page has to answer four things quickly: what it is, what it costs, which version you want, and how to take it.

The title and the first image should agree. The price should sit near the decision. Variant labels should sound like something a person would say. On a phone, add to cart has to be reachable without a hunt.

Long descriptions are fine when the photos have not already said it. If the page is busy, cut the extra modules before you add another one.
