   Sophia Open: los talleres presenciales y gratuitos que Carol lleva a los
   colegios. La página se cuenta como un viaje: una noche estrellada sobre la
   selva, una postal del lugar donde está ahora, un sello de «gratis», una
   ruta en marcha y una maleta con los talleres. También lleva aquí el bloque
   de la portada que la anuncia (.open-aviso).

   La parada actual se cambia en el HTML (sophia-open.html e index.html); aquí
   no hay ningún lugar escrito.
