# =============================================================
# Ordinis — build & push images.
# Path-aware CI: backend и frontend jobs запускаются только когда меняются
# соответствующие пути. Trigger downstream передаёт BACKEND_IMAGE_TAG и/или
# FRONTEND_IMAGE_TAG; infra-pipeline применяет helm upgrade с per-service
# overrides — сервисы которые не пересобирались не катятся.
