/* ============================================================
   NOCTURNE - couche partagee (tokens, base, primitives, header)
   ------------------------------------------------------------
   Extrait de css/home-nocturne.css : tout ce qui n'est pas du
   contenu de page d'accueil vit ici, parce que la fiche pro v28
   (css/profile-nocturne.css) a besoin exactement des memes
   tokens, du meme header et du meme tiroir mobile.

   Chargee AVANT la feuille de page :
     index.html    -> nocturne-base.css + home-nocturne.css
     business.html -> nocturne-base.css + profile-nocturne.css

   Aucune valeur de design ne doit etre ecrite en dur ailleurs :
   toutes les pages Nocturne lisent les var(--...) definies ici.

   Les regles marquees "REGLE §6" / "§7" viennent des sections
   correspondantes de guide/INTEGRATION.md. Elles ont demande
   beaucoup d'iterations : ne pas les "ameliorer".
