/* ============================================================================
   Actu Propfirm — refonte éditoriale type Google News (2026-08-05)
   D'après la maquette Claude Design « Actu Propfirm Mobile.dc.html ».

   Deux principes, pour que ce fichier serve de base au reste du parc VDL :
   - tout ce qui fait l'identité du site est une VARIABLE (accent, polices),
     injectée par base.html depuis site.yaml — le reste est réutilisable tel quel ;
   - thème clair/sombre par variables CSS, choix du visiteur en localStorage.
