The orbit was always a real camera orbit — figure and props share one rigid rotation — but a bar's screen-space angle authored the wrong 3D rod: the default horizontal encoded a rod along the body axis, so barbells hovered fixed on screen and vanished at the head-on view where they should span widest. Line props now take "axis": "z" (both renderers in lockstep, fixture-pinned): the world left-right direction projects through the camera pitch like the floor quad — end-on plates in profile, full span face-on, swinging with the hands in between. Applied to the ten cross-body bars; vertical handles were already orbit-invariant. Goblet Squat's hand pins sat so close to the shoulders that the two-bone IK was degenerate, flipping between a chicken-wing and an elbow-behind solve; re-pinned level with the shoulders so the elbows tuck straight down through the whole rep.
