   SUMMER TEENS · DEMO SESSION — Extended Learning ESAN
   Paleta tomada del mailing "Casting Nuevos Talentos" (new-talents):
   rojo #FF393A + negro #141418 + blancos y grises. Sin celeste.
   Estructura en bandas de alto contraste, al estilo de la landing de Open Day.

   NOTA: todo el rediseño vive en este archivo. No se tocó index.html, así que
   los textos que faltaban en el markup (menú y etiquetas de sección) se
   inyectan desde aquí con `content`, y los estilos en línea del formulario se
   sobreescriben con !important. Ambas cosas están marcadas más abajo.
