/* ============================================================
   MOBILE DRAWER — Sidebar polish para mobile (Sprint H)
   ============================================================
   Mejora el sidebar mobile que ya existía:
   - Backdrop overlay oscuro al abrir
   - Sidebar más ancho (280px de 260px) para mejor accordion
   - Animación slide con cubic-bezier elegante
   - Body scroll-lock cuando drawer abierto
   - Botón hamburguesa con badge "Menu"
