// Stop / restore: Owner-touch again to restore the startup snapshot before removing or resetting. A reset while previewing loses the original snapshot.
// Notes: Use a small nonphysical rezzed build with room around it. This changes real geometry, not just a viewer effect. Restore before reset, relink, or removal; a script-memory snapshot is not a permanent backup.
