Target-centered calibrated physical camera paths

Fixed initial target-aligned world-Z-up axes, translated to target center, metres. Overlap illustrates matching camera paths; no velocity, jerk, human gait or realism optimization claim. Missing first bend/yaw remains unavailable. Scenes are the statistical units; seeds are paired repeats. Bearing wraps are not reversals; direction reversal means adjacent nondegenerate horizontal moves bend more than 90 degrees.

Coverage: 12/20 intended paths; 6/10 pairs, 8 unreached paths. These descriptive paths do not independently establish renderer equivalence.
