/* FTR-012 Power-up locker (shop.js). Self-contained: it uses the site's variables from styles.css when present and the
   same values otherwise. The open locker is a navy twill patch with a gold merrow rim; each power-up is a black tape
   with a cream running stitch. Before $FTRG launches the locker is an unsewn pattern: a navy dashed outline on the
   orange ground with navy text (The Navy On Orange Rule). */
