   MENU MODERNE (maquette 12/11/2026)
   Barre flottante en « pilule » au-dessus du hero :
   - en haut de page : verre sombre, texte blanc (sur la photo du hero)
   - après défilement : verre clair, ombre, plus compacte
   - se cache quand on descend, revient quand on remonte
   - pastille qui glisse sous la section en cours (et au survol)
   - barre de progression de lecture
   - mobile : menu plein écran avec grands liens animés
   Couleur d'accent : --nv-acc (turquoise sur web, orange sur dépannage)
