   Portfolio de Paul Dumiot — feuille de style unique, mobile d'abord.
   Une seule famille de police (Mona Sans) dont on fait varier la largeur :
   très large pour les titres, normale pour le texte.
   L'élément signature est l'éventail-nuancier du haut de page : tout le reste
   reste calme pour laisser parler les exemples.
