/*
 * Bereini WebUI — ZINRAI theme + responsive shell.
 *
 * Loaded after bereini.css. Three parts:
 *   1. The ZINRAI theme (default), after the IIDX 34 site: neutral dark
 *      surfaces, one magenta accent and the slanted title plate. Glow marks
 *      what is active or earned (current nav item, focus, clear lamps);
 *      motion marks change (page entry, tab switch, press). Only the
 *      FULL COMBO lamp loops, as it does in the game.
 *   2. The mobile shell for every theme: sticky top bar + off-canvas drawer.
 *   3. Layout fixes that keep pages inside the viewport on phones.
