# Run Streamlit app on container startup
# --server.address=0.0.0.0      → makes Streamlit reachable from outside the container
# --server.port=8501            → fixed port
# --server.enableXsrfProtection=false → needed for batch API calls (HuggingFace Spaces fix)

# NOTE:
# XSRF protection is disabled ONLY to allow batch API requests without failing.
