   PREICFES APP — LANDING DE INSTITUCIONES (/instituciones)
   ------------------------------------------------------------
   Escritorio primero: quien llega es un colegio (rectoría,
   coordinación) que decide desde el computador; el celular se
   resuelve con media queries de max-width al final.
   La demo es la protagonista: CTA en el encabezado, en el hero,
   en cada módulo, en la franja de demo y en un botón flotante.
   Colores solo con tokens de preicfes-tokens.css. Prefijo ie-.
   Los formularios reutilizan los componentes .ob-* del embudo.
