+Very small launcher for the Space.
+
+If you followed the earlier guide and added src/ui/gradio_app.py
+inside your package, just import its `launch()` helper.
+
+Otherwise (or while you’re still developing) uncomment the
+‘quick-and-dirty’ block at the bottom; it builds a trivial UI
+inline and will work as long as the core library is on PyPI.
