1. Drag a slider on the Model half. The plasma outline above follows at once.
2. Full Rebuild. Runs main.py with these values — about half a minute — and the CAD tab shows what it built.
3. Ask. Hover a row to trace what it feeds; Discuss config hands these numbers to Becky.

This design carries its PROCESS study too: the PROCESS half is the solved run, and the marks on the sliders say which numbers came from it.
