Zombie town: the match continues

Win your first game and the applause cuts off mid-clap. The palette drains,
the umpire lowers his voice ('Quiet... please'), your opponent turns — torn
red polo, dragging his racket — and shamblers come over the billboard wall.
The scoreboard rewrites CPU to THEM. 'Play.'

- zombies.js: shamblers walk your way; quality shots splatter them (gore
  decal + particle burst + wet synth splat), weak sitters only stagger them
  back; one crossing your baseline is a point for THEM
- tennis scoring machinery keeps running untouched: fifteen, thirty, deuce,
  and 'Game, set... massacre' on a game win, all in recorded umpire English
- ball boys mop the gore they pass (their destiny fulfilled)
- transition: palette lerp, scripted spawns incl. the turned opponent,
  new recorded lines (quiet_dark, remain_seated, play, new_balls)
- moan ambience, drained splatter palette, all zombie params in TUNE

Verified: transition triggers on first game win, splat/stagger/baseline
scoring all correct, dead-ball flow feeds fresh serves, tennis mode
regression clean (6/6 returns, 6/6 points resolved).
