   Pantallas de acceso: login, registro, recuperar y restablecer contraseña y
   confirmar correo. Solo se carga en body.auth-page (ver includes/header.php)
   y el marcado vive en includes/auth_shell_open.php.

   Computadora: dos columnas a pantalla completa. La marca, fija a la
   izquierda, muestra el producto; el formulario, a la derecha, queda solo
   sobre blanco y centrado.
   Teléfono: la marca se reduce a una cabecera corta y el formulario sube
   como una hoja, con correo, contraseña y botón visibles sin desplazarse.
