/* ============================================================
   HEADER-PUBLIC.CSS — En-tête unifié des pages publiques
   ------------------------------------------------------------
   Reproduit fidèlement l'en-tête de la landing (index.html) afin
   d'offrir une expérience visuelle cohérente sur toutes les pages
   publiques (À propos, Abonnement, Contact, Ressources, etc.).

   Le markup est injecté par inject-header-public.js à partir du
   composant assets/components/header-public.html.

   IMPORTANT — Source de vérité visuelle :
   Ces règles sont alignées sur le bloc HEADER de
   assets/styles/landing.css (classes .landing-header*). Si le design
   de l'en-tête de la landing évolue, répliquer ici pour éviter toute
   divergence entre l'accueil et les autres pages publiques.

   un vide visible sous l'en-tête, surtout sur mobile. */
