/* Preloved Bookstore
   One idea carries the page: a secondhand book is judged by its spine and the
   price pencilled on a sticker inside the cover. Every row is a spine (colour =
   genre family, the same colours as the genre filter) plus a price sticker.
   Everything else is kept quiet so those two things read first. */
