// Setup: Use a spare emitter prim with local Z pointing upward. Owner-touch toggles. Uses the default particle texture and does not require a water asset.
// Stop / restore: Touch to clear the emitter before removing. Stop particle effect can clear a stranded emitter.
// Notes: Viewer-only droplets do not collide or make water. Uses about ten particles per second. Prior particle settings are not saved.
