   blog.css — Feuille de style du blog Quentin Dulout Courtage
   Copie stricte du CSS inline de index.html (mêmes variables, mêmes polices,
   même palette, même header/footer), complétée en fin de fichier par les
   styles propres au blog (liste d'articles, corps d'article, FAQ, fil d'Ariane).
   Aucun style existant n'est modifié : les ajouts sont additifs.
