/* ==========================================================
   Max Ferrand · Performance — v6 "LE CARNET" (fond papier clair)
   Reconstruite le 11/07/2026 à partir de la spec persona
   (audit design 05/07 vs sites d'agences pro).
   - Fond papier #f4f1ea partout, PLUS d'alternance mécanique
     de fonds de section.
   - Flat print : filets 1px, hairlines, encarts encre pleine
     (offre phare = fond encre noire). Zéro ombre néo-brutaliste.
   - Navbar papier + hairline, footer encre = couverture du carnet,
     wordmark géant en pied de page.
   - Accent unique : bleu cobalt #0e3fd0.
   AUCUN 3D / Lenis / GSAP : scroll natif, texte toujours lisible.
