; Bull back-kick impact — the one-shot combined dust + stones + sparks thrown behind the kick.
; A composite effect: the root emitter is the dust; the "stones" and "sparks" child emitters fire
; with it (one_shot_effect.gd arms every CPUParticles3D in the scene). Fired via
; Fx.spawn(&"bull_kick", xform); the spawn transform aims local -Z along the kick-back direction.
; The bright flash-pop is a separate coded effect (bull_impact_fx.gd). Tune all three looks here.
