   91STUDIO — RESPONSIVE v7.0.0 (Apple HIG)
   Breakpoints : <480 phone | <640 mobile | 640-1024 tablet
                  1024-1440 laptop | 1440-2560 desktop | >2560 ultra

   STRATEGIE OVERFLOW MOBILE :
   Les wrappers modules gardent overflow-x:hidden (contient dans viewport).
   Les enfants internes (tables, tabs) ont overflow-x:auto pour le scroll.
   Les toolbars/navs sont contraints avec max-width:100% + flex-wrap.

   STRATEGIE TABS MOBILE :
   Les barres d'onglets (6-9 boutons) sont remplacées par un <select>
   natif sur mobile. Le JS (mobile-nav-dropdown.js) crée un select
   miroir et synchronise l'onglet actif. Le CSS masque la barre
   et affiche le select uniquement sous 640px.

   SIDEBAR MOBILE :
   Swipe-to-close, auto-close on nav, plus grandes touch targets.
   Bottom nav pill avec touch targets 44px+.
