   Anthony Cosson — Portfolio acquisition & marketing digital
   Direction artistique : monochrome sobre
   · Fond blanc, textes en noir et gris. Les couleurs viennent du CV : vert
     pour les boutons, les accents, la barre de navigation et le pied de page,
     or pour les particules (constantes GOLD_ de orb.js), le point du logo, la
     barre de progression et le filet du pied de page.
   · La hiérarchie vient des surfaces (blanc, gris clair) et des filets, sans
     ombre portée.
   · Typographie : Geist 400/500 (titres toujours en 500) + Geist Mono pour
     les relevés de type « instrument ».
