/* Je suis en règle · direction artistique « registre officiel modernisé ».
   Papier ivoire froid, encre vert-noir, vert registre profond et filets de laiton, comme la couverture toilée d'un registre.
   Instrument Serif pour les titres, en grand corps éditorial ; Instrument Sans pour le texte, les folios et la numérotation.
   Tout est tenu par des filets, des chiffres romains de section et des entrées numérotées N° 01 à 13 ; le sceau coché sert de signature.
   Les treize marques gardent leurs couleurs : le hub les encadre sans les imiter. */
