Gallery product card layout

A new product card layout - Gallery. On a computer the card shows just the product photo; when a shopper points at it, the second photo appears and the name, the short description, the price and an add-to-cart button (or "Choose options") rise over the bottom of it. On a phone the name and price sit under the photo. The cards sit almost edge to edge. Pick it in Products → Product cards - for the whole shop or for one category - or press Customise to change it. The card layout editor also gains "On hover", "Description lines", "Minimal" spacing and "Second photo".
