   Porcelaine et bleu canard : la page est le plan de travail sur lequel la maquette
   (socle bleu canard, cuivre, laiton, chêne) est posée. Encre bleu canard, un seul
   accent, le cuivre (#9C4F27), utilisé avec parcimonie. Système tiré d'UI/UX Pro Max
   (« luxury bathroom », exaggerated minimalism) ; le bleu + orange proposé d'abord est écarté.
   Titres Cormorant Garamond, texte DM Sans.
