# ─── TRIGGER DEPLOY (downstream pipeline) ──────
# GitLab quirk: variables: в trigger job НЕ интерполируются от upstream global
# variables напрямую — `$IMAGE_TAG` передавался как литерал. Workaround:
# resolve-tag job записывает значение в dotenv artifact, тогда оно становится
# job-level variable trigger job'а и interpolation работает.
