   Règles de design (inspirées des sites B2B de référence) :
   1. une seule couleur principale (bordeaux) pour boutons et liens ;
   2. pas de dégradés décoratifs, jamais sur le texte ;
   3. des neutres légèrement teintés (gris rosé), ni noir ni blanc purs pour le texte ;
   4. une bande sombre pour rythmer la page (contact + pied de page) ;
   5. le produit au centre : captures cadrées comme des fenêtres d'application.
