详细描述

CPU-authoritative strand buffer (UE FHairStrandsDatas analogue).

Points are dense; each curve references a contiguous subrange. Optional per-point attributes can be added later without changing curve indices.

@thread Affine to the owning asset/instance; no internal synchronization. @reentrancy Does not invoke callbacks.
