/*
 * The shelf (wishlists/_shelf): Minhas listas and a friend's page. A warm
 * wall with two planks of three spots; each list on display is a drawn gift
 * box in its colour (list-color-*, --c), with a pattern, as tall as what's
 * inside (fill-0 to fill-12), a paper label and a little tag for who sees it.
 * A free spot is just plank. Beside it, the band's cards. Below, the lists
 * off the shelf, three rows at a time (show_more_controller.js).
