/* ============================================================
   catalog.css — Página categoria.html (catálogo + filtros)
   ------------------------------------------------------------
   Inspiração visual (smartgr collections/*):
   - Banner do topo com título da coleção + descrição
   - Facets (filtros) em <details>/<summary> com checkboxes
     dentro de listas; no desktop horizontais no topo, no mobile
     em drawer/modal
   - Sort dropdown no canto superior direito do grid
   - Grid de produtos padrão (4 cols desktop)
   Adaptação europeptídeos:
   - Sidebar fixa à esquerda (280px) no desktop (mais útil pra 3
     dimensões de filtro com pouca quantidade de valores; evita
     o overhead de <details> empilhados horizontalmente).
   - Mobile: sidebar vira drawer da esquerda com scrim + Esc,
     mesmo padrão do header.js.
