Splatter feel pass: baseline turret, tennis duel, rapid serves, bleeding wounds

- Stand at the baseline: in splatter the player is pinned to the baseline
  (a turret, side-to-side only) — the duel is exempt so it keeps free depth.
- Zombie 1:1 duel now plays like real tennis: no free-aim flick, no drag
  reticle; lane aim + the toss-then-hit serve (gate on !G.interlude in
  doHit/hitServe/keyPressed/canAimServe).
- Rapid serves: the two-stage reticle serve now fires mid-rally too — a ball
  still in flight is banished to a ballistic clone so the next serve launches
  at once. Serve as fast as you can drag-release.
- Wounded skins for multi-hit foes: brute (arm off) and racket boss (arm off,
  then headless) swap by remaining hp, with a graceful fallback to the healthy
  sprite. The headless boss is drawn a head shorter so the shoulders line up.
- Dynamic gore: the blood is NOT painted in — open wounds gush live particles
  every frame (arm stumps + a neck geyser on the headless boss), absurdly, and
  bounded so it self-regulates.
