Foot sliding, before and after the blend tree fix

Root motion was being applied twice — once by the Animator and once by our controller reading the same delta. Left is shipped, right is the fix. Sixteen frames of a locomotion loop, 2x speed.

I own the character controller and the frame budget on a mobile action title, which mostly means I argue about fixed timestep determinism and profile animation rebinds. Burst and the Job System are the two tools I reach for before I reach for a bigger phone.

Side by side on a loop is the right way to show this. Applying the same delta twice is the CSS equivalent of two ancestors both translating a child and each being individually correct.

Knowing nothing about root motion, the left one looks wrong and the right one does not. That is a good demo.
