/* Booklist & Display Designer.
 *
 * Two halves. The workspace around the page (side panel, toolbars, lists)
 * takes its surfaces and type from the site preset like every other tool.
 * The SHEET does not: it is a printed object with its own palette and type
 * pairing (booklistmodel.js PALETTES/FONTS, passed in as --bl-* custom
 * properties on the sheet), measured in inches so that what is on screen is
 * what comes out of the printer. A sheet is drawn at true size and scaled
 * down with a transform; nothing inside it is sized in screen units.
 *
 * Sheet rules are scoped to `.bl-sheet`, not the product element, because
 * the print copy is put on <body> directly (see printNow in booklist.js).
