/* 3D Morbihan : « Filament ».
   Idée de mise en page : une page claire tenue par un seul fil orange qui part de la bobine du premier écran,
   longe les marges, traverse la page à chaque changement de section et finit dans la buse, au-dessus du devis.
   Couleurs : papier, encre, un fil orange, un fil vert. Rien d'autre.
   Polices : Urbanist (titrage, graisses 600 à 800), Source Sans 3 (texte courant et chiffres tabulaires). */
