fix(site): render the map without transitions when printing

The box strokes fade from screen to print colors over 0.15 s, and the PNG/PDF render sometimes captured them mid-fade. That made the output differ slightly between runs and the map fingerprint flip, which created an unnecessary release (v2.0.2). Print styles now disable transitions and animations, so 12 of 12 test renders are byte-identical.
