TODO_hf_fix_gradio_errors.md

- [x] Fix import error: `No module named 'model'` by making HF `sys.path` injection robust in `app.py`.
- [x] Push rebuild updates to HF Space.
- [ ] Next: address missing *weights* in HF runtime (space has only code files). This requires either:
  - adding a small script/logic to download weights from Hugging Face at runtime (using `snapshot_download`), AND/OR
  - ensuring your weights exist in the Space repo under a mounted `checkpoints/` path.
