Balance pass + 40-year soak test
- Power consumption x4: the grid now matters from mid-town on - Realistic tax multipliers, trimmed service upkeep: profitable cities - Buildings may claim empty zoned plots (services fit downtown) - Land value ladder: maturity bonus, size-scaled upgrade sampling, thresholds 34/74 -> full L1->L2->L3 density progression - Soak test: 40 simulated years, 11/11 asserts green (848 citizens, 7 L3 towers, $190k surplus, proactive grid growth, 1.2ms avg tick)
