   Zones géographiques.

   Même logique que le centre de contrôle : la carte occupe l'espace, le
   panneau de droite bascule entre la liste des zones et le formulaire de
   tracé. On ne montre jamais les deux — tracer et consulter sont deux gestes
   distincts, et les superposer encombrerait les deux.
