/* ═════════════════════════════════════════════════════════════════════════
   mobile-fallback.css — Trezo (2026-05-21)
   Rend TOUTES les pages desktop (Dashboard, Trésorerie, Marges, Caisse,
   Chantiers, Factures, Fournisseurs, Cautions, Marchés, Ledger, etc.)
   utilisables sur iPhone Safari / PWA.

   Stratégie :
     - <768px : sidebar masquée, sortie via hamburger overlay
     - main occupe toute la largeur
     - tableaux : scroll horizontal forcé (.table-wrap)
     - grids → stack vertical
     - bottom-nav universel injecté par JS (mobile-bottom-nav.js)
     - tap targets ≥44px, polices lisibles, padding bottom safe-area
