/* CyberForge Arcade — Mobile header & search-popup styles
 *
 * Loaded after styles.css and searchBar.css so its rules win on small screens
 * without `!important` wars. Strategy:
 *
 *   - On wide screens (>640px), keep the existing inline `.filter-bar` and
 *     hide the mobile search trigger + modal.
 *   - On narrow screens (<=640px), hide the inline filter bar entirely and
 *     show a compact magnifier-icon button right next to the Menu button.
 *     Pressing it reveals a centered modal that hosts the `#searchInput`.
 *
 * The four top-level controls (Menu, Search trigger, 🎨 theme toggle, ☰ genres)
 * are anchored individually (existing fixed positions for theme/genres remain),
 * so spacing is enforced by horizontal offsets on each button rather than a
 * flex container — that keeps backward compatibility with the existing layout.
