// Setup: Put in a child offset from its root. 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. TARGET_LINEAR ignores the non-DROP trajectory controls and acceleration. Targets only this linkset root, never a visitor.
