"""Hugging Face Spaces entry point for the UI shell.

Spaces runs the file named in README.md `app_file`. We point that at THIS thin wrapper so the
existing backend `app.py` stays the source-of-truth for the backend workstream and is never the
Space entry. All this file does is build the `ui/` demo and launch it.

Gradio 6 takes `theme` / `css` / `head` on `launch()` (not on the Blocks constructor), so we own
the `launch()` call here to guarantee the dark theme + Chart.js/flip `head` injection are applied
exactly as they are locally. `demo` is exposed at module level for tooling (`gradio deploy`).
