   HERO — IMAGES DE FOND
   Technique : on définit --hero-bg-url en style inline dans le HTML,
   et on utilise un sélecteur universel pour appliquer l'image.
   Cela évite de créer un bloc CSS par page.

   Usage dans le HTML :
     <div class="hero hero-page" style="--hero-bg-url: url('images/blois-chateau1.jpg')">

   Variantes d'overlay disponibles (à ajouter à la classe .hero) :
     .overlay-warm  → rgba(31, 24, 18, 0.45)  — pages patrimoniales
     .overlay-dark  → rgba(31, 24, 18, 0.48)  — pages médiévales/religieuses
     .overlay-sea   → rgba(18, 46, 68, 0.50)  — pages côtières/urbaines
