 * Cover frame. Almost every cover is a 4:5 photo of the book on a near-white
 * backdrop, so the frame takes that shape, loses its padding and lattice, and
 * matches the photos' own backdrop: a 4:5 cover fills it edge to edge.
 * A cover of another shape is shown whole over a blurred copy of itself
 * (books-filter.js marks it and hands over the image), so no frame shows round it.
