   MISIGAD — LOGIN
   Archivo: css/login.css

   Mismo sistema visual que los módulos del docente:
   azul institucional como único acento, tarjetas planas con
   borde de 1px y radio de 8px, etiquetas en mayúsculas
   pequeñas, campos como el buscador del header y avisos con
   los mismos colores de éxito / error.

   El login no carga styles.css, por eso aquí se definen los
   mismos tokens.
