   MODE NUIT
   Le site est dessine pour le jour : fond blanc, texte charbon. En mode nuit,
   les variables de la maquette changent de valeur, et les surfaces qui portaient
   un blanc ecrit en dur sont reprises une a une. Les blocs deja sombres — pied
   de page, bandeau d urgence, section « engagement », appel a l action — ne
   bougent pas : ils font deja partie du dessin.
