During an RMB path-follow the body yaw locks to the leg direction (rig
commit_body_to_motion, from interpolated velocity — immune to SetFacing
interleaving between throttled steps). The mouse instead drives a layered
look-at: LookAtModifier3D pair on Head (±70°) + spine_02 (±30° torso twist
for looking far lateral/behind — past their sum the character physically
cannot look further without turning). Forward axis measured from the
armature rest pose (+Z), not guessed. Influence fades in/out on follow
start/end. Pure client presentation per D-249; SetFacing still rides the
wire, so the server vision cone follows the mouse while walking — the
character looks where the player points.
