The staff learn your habits, the walk-on waits for your tap, and the club opens a practice court

Four answers to one phone report:
- THE READ: repeat a lane and the opponent anticipates it; break the habit
  and it is wrong-footed for that ball — scaled by rung, so surprise is the
  weapon that opens the ladder past the HEAD COACH (TUNE block THE READ).
- The opponent walk-on is a real modal now (head, punchline, tap to dismiss)
  in arcade, tournament and training — readable without a clock.
- THE TRAINING COURT: third card under ZOMBIE TENNIS, pick any rung, one
  game at a time, the felled body walks straight back on, nothing banks,
  bleeding out is a popup instead of a death. mode_train.png rolled in the
  banner style.
- MOVEMENT READS: sprinting feet kick per-court dust and fast bodies leave
  a two-ghost speed streak (trailMin gates both; feel verdict pending).
