   auth.css — Acceso al panel de gestión de GECOTEL.

   Adaptación del sistema de acceso de la tienda (`tienda/src/public/session/css/auth.css`)
   a la identidad del panel: navy #0d1727 y dorado #c78300, los mismos tokens de
   `assets/css/admin-ui.css`, de modo que el login anticipe el panel al que se entra.

   Se usa en:
     - /index.php                    (inicio de sesión)
     - /session/autenticacion.php    (verificación en dos pasos)
