Three more chapters, and at game 100 the champion returns everything

The roster ran out at chapter 6 and then repeated itself; game 70 got the
groundskeeper again, bigger. bossArt() now walks nine designs, one per chapter,
and hands out THE CHAMPION on every tenth — the floor(ch/10) term takes his
chapters back out of the count so chapter 11 opens the second lap on the
groundskeeper rather than skipping him.

  70 THE STRINGER — leather apron, bandoliers of gut string, racket frames on
     his back. He takes your lane and puts two dead-straight ones on it.
  80 THE TOURNAMENT DIRECTOR — blazer, lanyard, radio. `adds` is new: he calls
     stewards onto the court while you fight him, which is the one thing a boss
     fight could not do before, since the stage is cleared for it.
  90 THE STRAWBERRY SELLER — tray of cream, apron soaked red, ladle. A tank
     that sprays four at once and then comes for you.
 100 THE CHAMPION — torn whites, a laurel of strapping tape, the trophy still
     in one fist. `rally`: anything under splatter quality comes straight back
     at your head, so he is the one body you have to out-HIT rather than
     out-shoot. `phases` lays three rows over his own as his health falls — he
     holds the baseline and rallies, then runs the line drilling volleys, then
     drops to a charge — and each turn is an event: cry, shake, the stand up.

Thirty-six frames through assets/_regen.py, the mascot's three-batch recipe
(2 stride, 3 wounds, 4 throws). The trap that cost the re-rolls: a throw batch
references its own wound frames, so a wounds batch that fails leaves the throw
sheet drawn against the SEED — two of the four came back half groundskeeper.
Wounds first, verify, then throws.

And the physio, who Oliver reported "does basically nothing but move towards
the net": he kept 4.2 of every 6.3 m he charged, so the fight was always over
before he arrived. `withdraw` is his own number now (0.2) and he charges half
again as fast — measured, he is on top of you in 11 s instead of never — and he
drills three balls a cycle on the way in.
