- CarteController : index() + data() (JSON) — requête lieux géolocalisés
  ayant des sources avec relevés, agrégats par lieu
- Lieu model : relations sources() et releves() (hasManyThrough)
- Vue carte/index.blade.php : carte Leaflet pleine hauteur, marqueurs
  colorés par nombre de sources (taille/couleur proportionnels),
  popup par lieu avec liste des sources, statuts, années et lien recherche
- Tuiles OpenStreetMap inversées en mode sombre
- Route GET /carte + GET /carte/data
- Lien "Carte" dans la navigation desktop et mobile
- @stack('head') dans le layout pour injecter Leaflet uniquement sur la page carte
