// 근거: 런타임 실측(2026-09-07 00:3x) — applyRootMotion=true 인데도 Knight@Attack1~3_S 클립의 animator.deltaPosition 합 = 0.000 m
//       (Chase_Start 1.996 m · Run 0.124 m 는 정상). 클립에 MotionT 커브(hasMotionCurves=True)가 있어 Unity 가 RootT 대신
//       움직이지 않는 모션 노드 커브를 루트모션으로 쓰기 때문 → 모션 노드를 None 으로 두면 RootT(실측 0.30 m 등)를 쓴다.
