   loginAccess.css
   Pantalla de acceso al sistema (login.jsp)
   ------------------------------------------------------------
   Hoja propia de la vista modernizada. NO reemplaza a login.css
   ni a menu-login.css, que siguen sirviendo a loginOld.jsp,
   login18.jsp y mobile.jsp.

   Todos los colores consumen tokens de theme-vars.css. Los
   fallback de var() estan puestos porque esta pantalla se
   renderiza antes de que exista sesion y el tema podria no
   haberse resuelto.
