+"""End-to-end smoke test: launch OrcaSlicer with the automation server, load a
+model, slice it, wait for completion, and save both a window PNG and a 3D PNG.
+
+Run:
+    python example_slice.py --orca /path/to/OrcaSlicer --model /path/to/cube.stl
+
+On Linux CI, wrap with a virtual display, e.g.:
+    xvfb-run -a python example_slice.py --orca ./OrcaSlicer --model cube.stl
