/* =====================================================================
   CORRECCIÓN DEL REPRODUCTOR
   `.vp` traía `position: relative` con la misma especificidad que
   `.ratio > *` y, al ir después en el archivo, ganaba. El iframe salía
   del marco 16:9 y quedaba en su alto por defecto (150 px): el video se
   veía como una franja diminuta bajo un rectángulo negro enorme.
