Layers 1–2 (house, street) are illustrative — procedural, no coordinates, swap freely. Layers 3–6 (neighbourhood, city, watershed, global) are geo-anchored — solid blue lines mark a shared geocoordinate between them, so the same place can be re-rendered at any of those four scales. The dashed line is a separate thing: a resource flow (sewage, stormwater, a supply chain) running the full stack regardless of which layers happen to be geo-anchored. Try switching the place below.
