Headless screenshot harness renders Home, Gameplay, and a denser
score-chase board to PNGs at 1290x2796 (iOS) and 1080x1920 (Android),
in English with a real font loaded. Captures the boundary layer at 3x
inside runAsync (the only way it completes under the test binding).
Season-map cut deferred — its scrollable build stalls headlessly.
