// Setup: Put in a nonphysical root. Rotate manually, choose Capture A/B, then recall either bookmark. Home restores startup orientation.
// Stop / restore: Use the Restore or Home action described in setup before removing or resetting if you want the startup appearance. Menu listeners expire after 45 seconds.
// Notes: Local owner-only control. Saved snapshots live in script memory and are lost on reset. Bookmarks are rotations only; position and child-local transforms are not captured. Do not use on physical objects.
