   SHELL: mobile-topbar.css
   Mobile topbar + drawer lateral.

   Estado actual: el mobile topbar está OCULTO en mobile (Duolingo
   pattern — bottom nav es la única navegación visible). Pero las
   reglas están aquí porque podríamos reactivarlo, y el drawer sí se
   muestra cuando el usuario tap-hold para abrir un slide drawer.

   Elementos:
   - .mobile-topbar (fixed top container, currently pointer-events: none)
   - .drawer-overlay (full-screen dim) + .overlay-visible
   - .drawer-panel (slide-in panel) + .drawer-open
   - .drawer-header, .drawer-user-info, .drawer-avatar, .drawer-name,
     .drawer-plan
   - .drawer-nav, .drawer-link (+ :hover, .active)
   - .drawer-divider, .drawer-footer, .drawer-logout
   - @media (max-width: 768px) toggle visibility
   - Dark mode
