User scenarios in the real UI, headless: scenario::Harness draws the app frame by frame into an egui context and drives it with control-channel input (toolbar starts, clicks on world/sketch/origin-plane/axis points, keys, typing, drags) and checks the model; tests/scenarios/*.json: box with fillets, shell and hole; revolve on XZ; sketch on a face and cut; mirror; delete and undo. Control: ui.at, ui.dialogInput. Fixes found by them: a shape started on an existing point (the origin, a corner) is tied to it; the Dimension tool's value is edited in place with the value selected, so typing replaces it
