# Load .env file from project root
# Path: MiroFish/.env (relative to backend/app/config.py)
#
# override=False is deliberate: real OS environment variables must win over the
# .env file. The Docker deployment feeds configuration into the container through
# the environment — docker-compose injects the vars from `.env` via `env_file:`
# (and NEO4J_URI must point at the compose service, e.g. bolt://neo4j:7687, not
# the localhost value that is only correct for native dev). With override=True a
# stray/baked .env would silently clobber that injection, so the backend would
# dial localhost inside the container and never reach the neo4j service. For
# native dev nothing changes: those vars aren't in the OS env, so .env still loads.
