## Movement smoke (windowed): walks the guard to the entrance to check step-up,
## measures precision-walk speed, and checks footstep/landing cues. The guard
## reads captured-mouse input, so run it windowed:
##
##   godot --path . --script res://src/test/smoke_movement.gd

## Exit code 0 = pass, 1 = failure.
