/* ============================================================
   ROSA — "Notre Collection" nav accordion menu
   Mirrors .lang-menu patterns (max-height transition, uppercase
   .7rem, letter-spacing .18em, gold-dark hover). Themed through
   the shared CSS variables, so body.dark applies automatically.
   RTL-safe: logical properties follow body's computed direction
   (pages set document.body.style.direction = 'rtl' for Arabic).
