// Setup: Use a small prim and move it gently in Edit after activation. Owner-touch toggles the emitter.
// Stop / restore: Touch to clear the emitter before removing. Existing particles fade according to their lifetime; use Stop particle effect if the starter was removed early.
// Notes: Viewer-only particles do not provide collision geometry. Uses a sparse emission rate and replaces any previous emitter settings. Without FOLLOW_SRC, already-emitted particles remain behind. No path is stored, exported, or associated with an avatar.
