"""Generate a white-background phone figure-eight calibration GIF.

This script builds the phone and the figure-eight path in 3D first, then renders
them through a simple perspective camera. The phone is a thin cuboid that moves
like a train on the track; the visible screen/back/side faces come from the
projection and face orientation instead of 2D shape rules.
