Redraw the player and the opponent

Both full sets through the same pipeline: stances and ball-bounce, serve toss,
smash and both swing frames, the four-frame run, and the five-frame death. The
opponent's ten frames with them. Inner-edge density roughly doubles across the
board — the serve frames go 0.22-0.32 to 0.41-0.54.

_regen.py retries a rejected batch itself now (default three attempts). A
rejection is usually just a bad roll — two figures drawn close enough that the
slicer sees one frame, or a limb off the canvas — and re-rolling fixes it without
me sitting in the loop.
