/* ============================================================================
   Portfolio v1 — feuille de style
   ----------------------------------------------------------------------------
   Organisation du fichier, dans l'ordre :
     1. Variables de couleur   — thème sombre par défaut, clair en surcharge
     2. Base                   — remise à zéro, typographie, sections
     3. Header                 — logo, navigation, bouton de thème
     4. Hero                   — grand titre en pleine hauteur d'écran
     5. Cartes de projets      — la grille et ses cartes
     6. Section à propos
     7. Formulaire de contact
     8. Responsive mobile      — le gros du travail est ici
     9. Transitions entre pages
    10. Archive                — blocs gris et bandeau, propres à cette copie

   Deux thèmes : le sombre est l'état de base, le clair vient le surcharger
   via :root[data-theme="light"]. Toutes les couleurs passent par des
   variables, donc un thème ne redéfinit que les variables, jamais les règles.

   Polices : Playfair Display pour les titres, DM Sans pour le texte.
