/* ==========================================================
   PORTFOLIO - styles
   Palette « Bleu sélection » :
     papier #F4F3EF, encre #121317, gris #5C5D63,
     un seul accent : le bleu de sélection des logiciels de design #2F5BFF
   Deux thèmes (clair et sombre) : les couleurs se règlent
   dans :root (clair) et [data-theme="dark"] (sombre).

   Système :
   - typographie : échelle fluide --step-*, une seule famille, Instrument Sans (comme le CV) ;
   - arrondis : 8px (petits éléments), 16px (images, cartes),
     28px (grandes scènes et panneaux), pilule (boutons) ;
   - une seule couleur d'accent, réservée aux boutons, liens et à la sélection.
