Zombies get faster over time; when one reaches you, you're eaten

splatT now ticks while in splatter mode and scales spawn speed by
1 + min(1.5, splatT/70). A zombie within 0.7m of the player ends the
run: gore burst, 'game, set, massacre', dark EATEN. overlay with final
games and a tap-to-restart (gated 0.7s so death-spam doesn't skip it).
Zombies keep shambling on the end screen but no longer score. Also
verified the two prior unverified items: quick-serve cadence (0.25s
between balls, flick = instant aimed serve) and flick aiming across
the net (far/near lane selection works as designed). HANDOFF updated.
