# .env has QDRANT_HOST/REDIS_HOST/NEO4J_URI/CELERY_* set to localhost, which is
# correct for running the app directly on the host against forwarded ports but
# wrong inside these containers (localhost there means the container itself,
# not its sibling containers). environment: overrides env_file: for the same
# key, so this repoints them at the compose service DNS names without having
# to touch .env.
