/*
 * Mobile navbar drawer — peer-checked fallback + polish.
 *
 * The compiled Tailwind bundle (tailwind-main.css) currently ships without
 * peer-checked variants, so the markup class `peer-checked:flex` on
 * #mobile-nav-drawer has no effect and the hamburger toggle never opens
 * the drawer. This file implements the :checked sibling selector directly
 * so the pure-CSS hamburger works regardless of the Tailwind build state.
 *
 * It also paints a polished mobile drawer: card-style surface, gradient
 * accent, slide-down animation, full-viewport backdrop, and a clearly
 * themed close button.
 *
 * Selector contract (do not change these ids without updating base.html):
 *   - #mobile-nav-toggle     : the <input type="checkbox"> driver
 *   - #mobile-nav-toggle-btn : the <label> that flips the checkbox
 *   - #mobile-nav-drawer     : the drawer panel that should slide in
 *   - #mobile-nav-backdrop   : the dim/blur backdrop behind the drawer
 */
