#   Use 'backend' service name from docker-compose.yml on port 8080

# DOCKER + EXTERNAL BACKEND:
#   Use host.docker.internal to access backend running on host machine
#   PYTHON_API_URL=http://host.docker.internal:5001
#
# DOCKER + PRODUCTION BACKEND:
#   Use Google Cloud Run production backend
#   PYTHON_API_URL=https://your-python-backend
