/* ============================================================
   BERUNDA — The Collection · The Filter
   Renamed from "Refine" → "Filter": one unmistakable, gold-foil
   control that reads as a filter at a glance. A sticky controls
   row sits beneath the nav (count on the left, Filter on the
   right); the button drops a velvet panel of gold-chip facets.
   ============================================================ */

/* the Filter sits in normal flow (it does NOT move with the scroll) and carries
   no bar behind it — just the button on the cream field. Its z-index is lifted
   above the gallery (1) and the dimming scrim (54) so the panel it drops always
   opens in FRONT of the products, never behind them. */
