Settlements now cost 3 / 4.5 / 6 gold per second in upkeep at Village and City tiers, while each completed Settlement road endpoint reduces upkeep by 1 gold per second.
Capitals produce 12 gold per second, Markets produce 10 / 18 / 28 gold per second, and living Houses retain a protected 5 gold-per-second income floor.
Settlement construction and upgrades are rejected without spending resources when their projected upkeep would cross that protected floor. Royal Engineers still cover purchase price, not ongoing affordability.
Gold tooltips and the Realm Ledger now show the complete capital, territory, Market, Settlement upkeep, and road-relief breakdown.
New roads prefer completed trunks when the shared route remains within the bounded detour limit. Shared stretches construct and render once without multiplying endpoint bonuses.
