/* The studio gallery (templates/public/includes/gallery_window.html and

 *
 * The opener covers a card's photo, its label in a corner. The window: nearly
 * the whole screen, dark, each photo whole in the middle; js/public/gallery.js
 * adds the arrows, keys and counter, js/public/dialogs.js opens it. It opens
 * only on new pages, so, like the class window, it keeps its own ::backdrop
 * (CONVENTIONS.md 6.14).
