Physical scale
Outdoor Mainframe rooms represent one hundred feet of city movement. Hillclimbs, stairs, descents, and tight vertical transitions use shorter beats so slopes and grade feel real.
Seattle / Mainframe
The city is the map.
The Mainframe is the permanent physical city. Streets, routes, bridges, stairs, docks, gates, and landmark anchors give the world distance and weight.
Landmarks
Major places begin as anchors and gates. Interiors can grow into full expansion areas when the city needs them. Seattle stays readable from the street outward.
