 * Desktop mega menu — Bootstrap 5 full-bredd dropdown.
 * Mobil (offcanvas) hanteras av offcanvas-menu.css.
 *
 * Princip:
 * - position:static på nav-item så dropdown positioneras mot navbar
 * - full-bredd panel med Bootstrap container+row inuti
 * - Ren typografi, tydlig hierarki: KATEGORI → underkategori
 * - WCAG: focus-visible ring, keyboard-navigation via Bootstrap 5
