/**
 * @file
 * MVSD Core — Mobile translate panel.
 *
 * Mobile-only companion to the desktop `.nav-translate` panel (layout.css),
 * which is display:none at <=900px — leaving phone users with no way to
 * translate the site at all. Adds a brand-colored globe button beside the
 * hamburger that opens a left slide-out panel mirroring #mobile-menu.
 *
 * The language rows are CLONED from the desktop `.translate-menu` at runtime
 * (js/mobile-translate.js) so the list can never drift from the desktop one.
 * Clones keep their `.translate-menu__link` / `.translate-menu__restore`
 * classes, so the base link styling in layout.css still applies — the rules
 * here only add the mobile sizing/layout on top.
 *
 * Nothing in this file touches the desktop translate system.
 */

/* ── Toggle button (sits beside the hamburger on the mobile bar) ─────────── */
/*
 * Hidden until JS has cloned the language list and added .is-ready, so a JS
 * failure leaves no dead button (the whole translate system is JS-driven).
 * A class is used rather than the [hidden] attribute because the UA's
 * [hidden]{display:none} loses to the display:flex rule below.
