# Auto-Ka — Agrégateur de voitures usagées à vendre (province de Québec)
# Auteur : Simon-Pierre Boucher — contact@spboucher.ai
# connectors/okaze.py : OKAZE (Saguenay) — site Webflow (CMS w-dyn-list).
#
#   Stratégie : la page /inventaire est rendue côté serveur avec TOUTES les
#   annonces (pas de pagination). Chaque carte embarque un <script> inline qui
#   pose des attributs data-* dont `data-search` : une chaîne CSV complète —
#     nom, année, carrosserie, catégorie, couleur ext., couleur int., marque,
#     modèle, moteur, portes, km, prix, motricité, transmission, carburant.
#   On parse ces cartes en HTML brut (regex) : une seule requête par sync.
