Keep the wounded walking, and make the steward worth his size

A wound skin was a single still, so anything hurt froze on one frame and slid
across the court. Every skin has its …b twin now — the stride swapped, stepped
off the same clock as the healthy walk — for both shamblers, both racket-zombie
stages, and the steward, who had no wounded state at all.

The steward also died like a shambler at 3 hp, which made a bigger body read as
decoration. Five now, with a wound skin to show the second half of that. hpMax
is recorded on every body that has hp, so "hurt = show the wound" is one rule
instead of a per-variant constant to remember.

First pass at the wound frames was rejected on sight and deserved it: the
generator drew small figures with fine pixels on a GRADIENT background, and a
nearest-neighbour downscale to sprite height shredded the outlines. Regenerated
two at a time, drawn large, chunky pixels, flat background, hard black outline —
then fitted per channel onto each frame's own healthy twin.
