# Assemble and push the Hugging Face Space.
#
# The Space gets only what it needs to run: app.py, the algotrader package, the
# Space card, and the minimal requirements file. The v1 agentic system and its
# heavy ML stack stay in this repo, so the Space builds in under a minute.
#
# Usage:
#   HF_TOKEN=hf_xxx ./scripts/deploy_hf_space.sh <hf-username>/<space-name>
#
# Create the Space first at https://huggingface.co/new-space (SDK: Gradio).
