HumanoidRetargeter/Core/Dl/SameStats.cs
A small data holder that loads normalization statistics from a SameWeights blob for the SAME checkpoint. It reads sixteen per-feature mean/std arrays (for positions, rotations, velocities, previous positions, etc.) and stores them as float arrays for later use in DL preprocessing.
