Polish round: modal system, softened palette, pixel font, and the 14 plan items

The three foundations first, since everything else leans on them:

- G.modal is the only thing that stops the world. update() early-returns on it
  so no zombie steps, no ball flight, no spawn timers run while a popup is on
  screen — you can read it without being eaten. Dismissal swallows the gesture;
  the pointerdown dismisser is registered only on pointer:fine, because on touch
  pointerdown beats touchstart and a shared handler cleared the modal and then
  served with the same thumb.
- UI in config.js is the accent palette. The arcade primaries were shouting over
  the artwork; the gore reds deliberately stay loud.
- Every canvas font string now goes through F(). Bare `monospace` resolved to
  Courier — a slab serif — which was the "generic serif" bug, not taste.

Then: weapons are only ever WON. deliverTin() has exactly one caller now
(resolveInterlude('P')); the old game schedule calls the DUEL instead, fired off
proceedAfterClear() where the court is guaranteed empty. Four popups (splatter
tutorial with a generated illustration, first duel, weapon received, horde),
wCap 9 with the tin amounts tunable, a 5-hp brute that comes apart over four
wound skins, fire that ignites the neighbours and chains outward, a three-stage
death where you become the biggest gore mound on the court, and a 7s changeover
with a ball boy who finally has a mop.

New art: assets/logo.png, x_howto, z_gw2-4, x_boymop1-4, plus assets/_key.py for
standalone art (chroma-key + crop, no frame splitting, no forced sprite height).

Benchmarks re-run and holding: CPU returns 23/24 serves, 30 human-tapped points
= 50 hits / 0 whiffs, 26 simulated games with no exceptions.
