/* ============================================================
   SAMA · blog.css
   Mise en page éditoriale du blog (liste + articles). S'appuie sur
   les variables/styles de base de style.css (reset, nav, footer,
   modales légales, boutons, palette) — ne redéfinit rien de la
   page d'accueil, n'ajoute que ce qui manque pour le blog.

   Parti pris : lecture longue confortable sur fond sombre (cohérent
   avec l'identité cinématographique du site), ponctuée de modules
   clairs ("paper") pour les éléments à scanner rapidement (chiffres
   clés, sommaire, citation, FAQ, CTA) — inspiré des meilleurs sites
   éditoriaux (longueur de ligne maîtrisée, hiérarchie typographique
   nette, contenu dense transformé en repères visuels).
