The previous thresholds (grass=60, smoke=70) required pollutionScore > 60. pollutionScore is a weighted average, so even if air pollution caps at 100 the score only reaches 40 from air alone — the thresholds were physically unreachable from furnace burning. New thresholds: grass degradation fires at pollutionScore > 15 (soilQuality gate raised to 75 so it doesn't block — soil defaults to 60), smoke particles fire at > 10. With 4 furnaces the score reaches ~15 in about 20 real simulation ticks (~2 minutes of play). Also added acid-rain water pollution (0.1/furnace/scan) — coal burning emits SO₂ which contributes to the weighted score alongside the existing air and ground components.
