/* ============================================================
   SHVJA — thème commun à toutes les pages
   Fusion de deux inspirations :
   - éditoriale (titres capitales serif, ornements, ambiance sombre)
   - énergique (menu avec burger + logo centré + pastilles d'action,
     cartes photo à gros titres, boutons pilule avec flèche)
   Chargé en dernier sur chaque page.
