Slowly orbit the camera around prop-free form guides

Bodyweight motions (no equipment layer, no hide list) now turn the
camera a full revolution every 24 seconds while the motion loops, so
the exercise reads from every side; machine exercises keep their
authored view, since scene equipment is a view-locked billboard and a
hide list describes a single viewpoint.

 **July 2026**
 
+Bodyweight form guides now slowly circle around the figure while it moves, showing the exercise from every side.
+
 The form-guide figures now have feet — heels rise on calf raises, toes point through leg lifts, and kneeling feet rest naturally.
 
 The Rotary form guide now shows a genuine torso twist, with the arms and bar swinging across the body.
