Clambering: capsule hips (Nimso), footprint takes the edge while pressing, knee-up memory

The box pelvis caught on ledge lips; a sideways capsule rides over. While clambering
(pressing, just pressed, legs tucked) the stance footprint may take higher ground the hips
are only partly over. Spike measures the free hand's error while climbing.
