Thumb-scale draw meter, looser aim magnet, a bomb worth the tin

- The draw meter is a fixed bar across the bottom, ~90% of the width and 10px
  tall, with the kill notch on it. It was a 26x4 stub floating on the apron by
  the player's feet, which is nothing under a thumb at arm's length. The serve
  hint is suppressed while pulling since they share the slot. pullFull 95 -> 130:
  at 95 every pull maxed out by accident, so the meter never meant anything.
- The aim magnet took the nearest body ALONG the lane, so a close shambler a
  little off-axis stole shots clearly aimed past it. It now picks the best
  ALIGNED body, with TUNE.aimTie of slack in which a nearer one still wins — a
  straight-ahead lane still eats the nearest body first, which is the settled
  feel. aimTie: 1 restores the old behaviour exactly, for A/B.
- Bomb radius 2.5 -> 4.2 (2 kills -> 5 in a scattered ten-wave), a 120-particle
  eruption, a ring of thrown stains and a full-size pile. The blinding white
  frame is now a brief warm bloom — it was hiding the very gore it announced.
- Rack tiles 22 -> 30 tall, and the touch band is padded above and runs to the
  screen edge below. At 22 logical px they were ~30 CSS px on a phone, well under
  the ~44 a thumb expects; now ~62.

26-game soak clean with heavy bomb use, arrays stay bounded. Serve returns
136/150 = 90.7% +/-2.4%, 30 human-tapped points = 50 hits / 0 whiffs.
