   STUDIO AMBULANCE — feuille de style propre au studio
   Parti pris volontairement opposé au Studio Taxi : grotesque technique au lieu
   de la didone éditoriale, hero scindé au lieu du bandeau photo sombre, rails
   numérotés au lieu des cartes à icône. Deux studios ne doivent jamais se
   ressembler — sinon ils se dénoncent l'un l'autre.
