@@ -10,6 +10,7 @@ The generator builds a city as walkable tile maps on four strata:
| Stratum | What lives there |
|---|---|
| Net | cyberspace: a dotted grid, a construct on every building, district hubs, link lanes, ICE at the gates |
| Heights | rooftops of the tall towers, helipads, bridges between them |
| Skyways | elevated walkways, mid-rise lobbies, platforms over intersections |
| Street | districts, arterials, blocks, buildings, markets, neon |

Heights. Districts have themes (corp core, night market, megablocks, combat
zone, docks, industrial, neon strip, old town) that drive street layout,
building mix, palette and signage. A Net graph of subnets, nodes and links is
anchored to the physical tiles and can be shown as a digital overlay. That
graph is the seed of the cyberspace side of the game.
anchored to the physical tiles and can be shown as a digital overlay.
The same graph is cyberspace. Jack in at any street terminal (walk up to it and
press `enter`): your body stays at the port and you emerge in the Net at the
same spot, in a wireframe world laid out one to one with the city. `enter`
again jacks out. In Explore mode `]` past Heights shows the Net.
Same seed and parameters always produce a byte-identical city.
