🏛️ Kyivan Rus Golden Age City Builder: Stone, Trade & Chronicles

Build a peaceful 11th-century city on the Dnipro: log houses, a brick-and-lime works, a gilded stone cathedral, a reconstruction of the Golden Gate and a timber pier. Send wax-and-fur convoys down the river to Constantinople, survive the spring flood on a raised platform, and read the equations behind it all (logistic growth, arch thrust, buoyancy, Rankine pressure, convoy time). History, trade and engineering only; every statement is marked established, debated or artistic licence.
