Lunar Base Power Grid 2D: Ring Distribution & Load Shedding

A lunar outpost's hardest power problem isn't generation — it's keeping every module fed through a 14.75-day night and around the occasional broken cable. This 2D ring-diagram simulator models the same microgrid connecting a solar array, a fission reactor and a battery bank to five habitat loads of different priority, running a real BFS reachability check and a priority load-shedding algorithm every frame. Toggle day/night, resize the battery, dial the flexible ISRU load, and click cables to fault them — watch the network reroute power around a single break (true N-1 redundancy) or go dark in an isolated segment when two breaks strand it, exactly the distribution and safety trade-offs real lunar base architectures have to design around.
