FX_Rotating shield.anim 측정 정합 (m_SampleRate 60·m_StopTime 2.8166666·총 169 frame).

PD 명시 영역 제어:
- intro: 1~88 frame (0~1.4667s)
- loop: 89~105 frame 반복 (17 frame·0.2833s)
- outro: 남은 frame (106~169 → 1.7500~2.8167s·1.0667s) — duration 종료 전 자동 재생

SpiritFireInstance.Init:
- Animator 캐싱·updateMode = UnscaledTime
- speed=1 (normalizedTime 직접 제어)

SpiritFireInstance.Update:
- elapsed < introEnd → linear sample
- elapsed < outroStart → loop range modulo
- elapsed >= outroStart → outro linear (duration - outroLength 영역)
- Animator.Play(STATE_HASH, 0, normalizedTime) 매 frame 호출

STATE_HASH = Animator.StringToHash("Base Layer.FX_Rotating shield")
