Brighter stands, a serve hint that shows the gesture, and a boy who walks

- The crowd sat in the dark, worst of all in splatter mode where you spend the
  game. Both crowd frames get an identical gamma lift (means 30/14/39 ->
  42/22/56) and the rot tint drops 0.5 -> 0.26. The curve MUST stay identical
  across the two frames or the clap swap flashes brightness; _sheet_crowd1.png
  keeps the pre-lift original.
- The splatter hint led with the tap when pulling is the whole gesture. It now
  reads PULL BACK TO AIM - RELEASE TO FIRE, and after 1.5s of sitting in the
  serve stance untouched a ghost thumb slides back while chevrons grow up-court
  on a loop. Pull back, shoot forward is an inverse relationship that a line of
  text cannot carry on its own.
- The mop boy has three sheets instead of two: the push cycle now plays ONLY
  while he is stopped and working, a new carry sheet walks him upright with the
  mop shouldered, and the run sheet stays for the tennis-mode ball fetch. He was
  mopping thin air the entire way to the stain.

Sheet note: frames 2 and 3 of the carry sheet merged (a mop handle bridging the
gap), so it is cut at the true column gaps plus the thinnest column inside the
merged pair, then common-scaled — same technique as the brute stride sheet.

26-game soak clean. Serve returns 133/150 = 88.7% +/-2.6%, 30 human-tapped
points = 50 hits / 0 whiffs.

+- **Crowd brightness**: both crowd sheets got an identical gamma-0.8 lift (means 30/14/39 →
+  42/22/56) and the splatter tint dropped 0.5 → 0.26. **If you ever touch one crowd frame you must
+  apply the exact same curve to the other**, or the clap swap starts flashing brightness.
+  `assets/_sheet_crowd1.png` is the pre-lift original.
+- **The splatter serve hint led with the tap** ("TAP TO SERVE · PULL BACK TO AIM") when pulling is
+  the entire gesture. Now "PULL BACK TO AIM · RELEASE TO FIRE", plus `drawPullHint()`: after
+  `TUNE.pullHintAfter` seconds of sitting in the serve stance untouched (`G.idleHintT`), a ghost
+  thumb slides back while chevrons grow up-court, on a loop. It teaches the inverse relationship
+  the text can't.
+- **The mop boy has three sheets now**, not two: `x_boymop` is the push cycle used ONLY while
+  stopped and working, `x_boycarry` is him walking upright with the mop shouldered, `x_boyrun` is
+  the tennis-mode fetch. He was mopping the air the whole way to the stain.
