Dockerfile

# Hugging Face Spaces image. Extends the official SIE server image, adds
# Node 22 for the UI server, and runs both processes from one container.
#
# This Dockerfile is HF Spaces specific. Local Docker users should use
# compose.yml (which just runs the unmodified upstream SIE image with the
# Node UI on the host).
