   VÍDEO DE FONDO DE SECCIÓN
   Se usa en Principios y en Recursos. La sección pasa de clara a oscura:
   el vídeo va al fondo, un velo lo apaga y los titulares se vuelven
   blancos. Las tarjetas siguen siendo blancas y opacas, así que su texto
   oscuro se lee igual y quedan flotando sobre el paisaje.
   --bg-pos encuadra el clip, como --conf-pos en las tarjetas: la sección
   es mucho más apaisada que un 16:9, así que el navegador recorta arriba
   y abajo y ese valor decide qué banda se ve.
