🟠 High — Performance

File: LegCorrector.cs

6 raycasts per frame (3 per leg × 2 legs) in LateUpdate adds significant CPU overhead, especially noticeable on lower-end hardware.

Fix:

Throttle to every N frames (e.g. every 2-3 frames): if (Time.frameCount % 3 != 0) return;
Or reduce raycast max distance
Cache Vector3[] allocations to avoid per-frame GC pressure
