/* ============================================================
   Portfolio - "Fog / Editorial Cream" design system
   Recréation du thème 21st.dev @syedmoin-lab/portfolio :
   charcoal + brume grise, typo grotesque massive, texte crème,
   minimalisme éditorial, pilules outline, cartes rounded-square.
   Police d'origine (propriétaire) remplacée par Archivo (libre).
   Fully self-contained, no runtime dependencies.
