/* =========================================================================
   Menú responsive — millora UI/UX + integració visual BSA  (2026-08)

   - Mòbil/tauleta (<=991px): panell off-canvas lateral amb capçalera de marca
     (blau BSA), ítems refinats, accent taronja actiu i submenús en accordió.
   - Escriptori (>=992px): desplegable per hover amb detecció de col·lisió.
   - El panell se situa PER SOBRE de la barra sticky (.upper-text té z-index
     999991) perquè, en obrir el menú amb la pàgina desplaçada, no s'hi coli
     el text fix "Treballa amb nosaltres".

   Carregat DESPRÉS de main.css i del bloc inline de meta.blade.php.
   Breakpoint únic compartit amb menu-responsive.js: 992px.
