# =============================================================================
# Frontend Next.js 14 (sortie standalone)
# =============================================================================
# RAPPEL CRITIQUE : NEXT_PUBLIC_API_URL est fige au moment du BUILD de l'image
# (next.config.js, bloc `env`). Une image construite pour la preprod pointera
# toujours vers api.preprod.xpeditis.com, quelles que soient les variables
# injectees ici. L'image du frontend doit donc etre RECONSTRUITE pour la prod,
# jamais promue depuis la preprod. Le workflow cd-main.yml applique cette regle.
