// Stop / restore: Touch to disarm and silence. It never changes movement or physics.
// Notes: Use licensed sounds in the exact prim containing the script. Playback is audible nearby. Asset loading and simulator timers can introduce delays; these are exhibit cues, not sample-accurate audio. Separate start/stop thresholds reduce chatter. Measures the object, not nearby avatars.
