Driver take over - real kinematics

Keys: W / up = gas, S / down = brake then reverse, A D / arrows = steer, space = stop, R = reset. Steering tightens as you slow; too fast in a tight turn tips the load. Live calls: curb strike, went wide, hit, tipped.

Deterministic kinematics rendered in 3D: forward moves steer the front axle, backing moves guide the rear axle; curb, apron, speed and load feed a simplified rub / rollover risk. Analysis tool, not a stamped engineering report - the licensed engineer signs in the review lane.
