   Product page (product-detail.html, js/product-detail.js).
   Desktop: a short dark band behind the breadcrumb; the gallery and the
   details on the left, a sticky buy card on the right, both overlapping the
   band. Phone: back link, swipeable photos, then the buy card, so the price
   and Buy now are on the first screen; a buy bar takes over once the buy
   buttons scroll away.
