Smoke asserts each icon's x and z against the sim position (non-symmetric, ships ride at y 50 and -90) and the yaw from the forward heading with a near-vertical rolled hull whose eulerAngles.y differs. MapPresenterCapture renders the scene's Map Overlays and Map Tint cameras to pixels. MapBeltPerf measures base (MapBeltPerfBase, verbatim AsteroidBeltUI) and head as median/IQR of 21 runs. All build.
