-The GUI can be published later as a Hugging Face Space pointing at this

+Public demo that can run fits (free)
+-----------------------------------
+
+Use Streamlit Community Cloud.
+
+1. Push this repo to GitHub (including ``autoemx/web/app.py``,
+   ``requirements.txt``, ``packages.txt``, and ``runtime.txt``).
+2. Sign in at https://share.streamlit.io with GitHub.
+3. **Create app** → this repository → branch ``main`` → main file
+   ``autoemx/web/app.py``.
+4. Deploy. The ``*.streamlit.app`` URL is the public demo.
+
+The app treats Community Cloud as a demo (banner, two-file cap, license).
+Fits still take 0.5–3 minutes. The first request may also build detector
+convolution matrices. Community Cloud has limited RAM; if the app is killed,
+reboot it from the Streamlit dashboard. Local ``python -m autoemx.web``
+remains the production GUI.
