/* Bon Tirage · direction artistique « âtre et suie ».
   Un foyer d'hiver : noir de suie, braise orange, brique et crème chaude, comme un âtre allumé un soir de décembre.
   Titres en Zilla Slab, une slab d'artisan solide et franche ; texte en Work Sans, net et lisible.
   Motifs dessinés à la main : appareil de briques, conduit de fumée, flamme et braises qui montent.
   Signature : l'attestation de ramonage tamponnée et datée, fil rouge de la promesse « certificat en main ». */
