Empirically tested delay thresholds (100/500/1000/2000/3900ms).
Delays under ~2s cause the engine's blend logic to accelerate the
Stand grow-in animation. 2000ms is the shortest delay that preserves
full-speed Stand across all 5 marker colors.
Also confirmed all 5 Raid_UI_FX M2 models have identical animation
sequence entries (Stand→Hold→loop chain via nextAnimation fields),
but the engine doesn't honor the chain — explicit PlayBoneAnimation
queue is still required.
