   STUDIO HERBORISTE — feuille de style propre au studio
   Troisième grammaire, distincte des deux autres : serif organique (Fraunces)
   au lieu de la didone du taxi et du grotesque de l'ambulance ; fond parchemin
   au lieu du blanc et du gris ; et surtout des ARCHES d'apothicaire là où les
   autres ont des rectangles nets. Aucun studio ne doit ressembler à un autre.
