/**
 * Facteurs de localisation du Québec (cost_locations). Module PUR.
 *
 * Main-d'œuvre : les conventions collectives de l'industrie de la construction
 * (Loi R-20, CCQ) fixent des taux UNIFORMES pour tout le Québec ; seuls les
 * chantiers isolés / Baie-James / Nunavik ont des grilles distinctes (APCHQ
 * publie ces grilles). Le facteur main-d'œuvre est donc 1,00 partout, sauf
 * régions éloignées (primes d'éloignement, hébergement — hypothèse).
 *
 * Matériaux / équipement : surcoût de transport et de disponibilité par
 * rapport à Montréal (référence 1,00) — HYPOTHÈSES documentées,
 * modifiables en base ; aucun indice public ne publie de facteur municipal.
