Encode the splatter bed too, and give the opponent his racket back

zombie-mode: 5.9 MB of 24-bit WAV down to 287 KB. Its master is 982597 frames
at 48 kHz, so loopEnd is the un-round 20.47077 — the decoder hands back
20.4787, and those 7.9 ms of AAC padding would tick once a loop. Nothing in
assets/audio/ is a multi-megabyte WAV any more.

o_run1/o_run2 had no racket in either hand. The cause was the batch prompt:
opponent_run never said "racket", and its reference sheet was built from the
racket-less frames it was replacing, so there was nothing to copy one from. It
is a ref_only batch off o_idle1 now — same man, front-facing, racket in his
right hand — with the subject spelling out that he still carries it mid-stride.
The stride reads as well as the old one did.
