/* ============================================================
   Launchpad de MFW: fondo de noche azul con la luz de MFW y las curvas
   de nivel de la entrada de Norte, y cuatro tarjetas con su dibujo.
   El cursor enciende la tarjeta por debajo y su borde. Sin librerías ni build.
   Fraunces en el saludo (la de títulos de MFW) y Geist en el resto,
   servidas desde aquí.
