# Celery worker and the acquisition cron migrate too, which they have no business doing.

# RENDER is set by Render on every service. Deliberately not reusing DATABASE_URL above:
# that answers "which database", not "which platform".

# Everywhere else — docker compose up, plain docker run — the start path is unchanged, so
