The serve gets stakes: tight apex window, depth rides quality, the strike flick aims

Three mechanical causes of 'no serve agency', measured then fixed:
- the 0.12 m perfect snap was ~0.3 s of hang time (now TUNE.apexSnap 0.05,
  and the gold band reads the same knob);
- the fixed mid-box target depth capped every good serve at ~36 m/s in the
  loft loop — player serve depth now rides quality, flush aims 0.3 m inside
  the service line (ladder: 49 / 52 hard / 36 mistimed / 30 bad);
- the strike flick was splatter-only — in tennis and the duel it now sways
  placement (horizontal) and buys pace (vertical, serveHard + serveHardSpin,
  the extra dive IS the clearance), paid for in scatter against the real
  fault machinery. Tap stays the safe second serve.

Phone verdict pending — see the PROJECT.md session log.
