   Les 6 étapes — système visuel
   -----------------------------------------------------------------------------
   Principes : une seule couleur d'accent (celle de la marque, réglée dans
   l'admin), des neutres froids, les couleurs d'étape réduites à un rail et un
   badge. Hiérarchie par la taille, le poids et l'espace — pas par la saturation.
   Grille 4 px, rayons 8/12/16/24, ombres douces, mouvements courts et
   interruptibles.
