TrajectoryFrame

Remarks

A wrapper rather than a sixth kind of frame, because "this goal moves" is orthogonal to "this goal is on a socket" — and every combination of the two is one somebody wants. A trajectory over a SurfaceFrame is a hand sliding along a rail; over a EntityFrame it is a hand tracking a thrown object; over a WorldFrame it is a scripted reach.

⚠ The base frame is resolved live and only the offset is replayed. The authored origin polyline is not played back — a rail that has moved since the clip was captured is the ordinary case, and replaying where it used to be would put the hand in the air.
