/* Portada pública del diplomado.

 * Hoja propia y sin dependencias a propósito: la portada comparte nombres de
 * clase con el diseño sitewide (.hero, .btn, .container, .section) pero no sus
 * medidas, así que mezclar las dos hojas rompía la maqueta. Aquí mandan los
 * tokens de diplomado-superior.institutoanippac.mx. */
