- Running: a foot stays down a moment and the leg bends like a spring, then
  a push off into a flight; the heel folds up under the seat and the knee
  drives through; the body rises and falls clearly, leans into it, arms pump
- Walking: longer steps, more arm swing

+- Running (`body.c`, `body_pose.c`): a foot stays down STANCE_RUN 0.11 s at a full run (`Foot.planted`; it was gone again after a frame or two, both feet nearly always in the air); the wave follows the ground contact - down while a foot is on the ground, up past standing height in the flight (BOB_FLIGHT; it averaged two opposite feet to nothing: the hips moved 1 cm, now 7 cm), BOB_RUN deeper; the swing foot follows a curve with the body (cubic: from where it left, RUN_TUCK up behind the seat, RUN_DRIVE through in front, down where it lands; `Foot.swing_run` set as it leaves and easing off with SWING_RUN_EASE - slowing down mid-swing no jump); more lean (0.2 rad at a run); the elbows about square pumping. Walking: steps longer (stepLength 0.3 + 0.27 x speed, MAX_LEAD 0.48), arms swing more (ARM_SWING 1.25), the elbow bends more coming forward. Checked: side views of a sprint, a jog and a walk; the audit (sprint pops 247 -> 125, worst 15.7 -> 18.3 cm; the rest about as before - walking and turning fast the hands move that fast in the world anyway).
