MPMapRendererConfig

[INTERNAL] The complete, immutable input of one render pass, snapshotted on the UI thread when the pass is scheduled: the camera (via the projection snapshot — viewport, zoom, bearing), the current floor, the map's max zoom, and the solution's render settings.

A pass reads only this object, so it describes one consistent (camera, floor) instant. It must never fall back to live map or floor state: other threads mutate that state while the pass computes, and a pass built from mixed instants renders a combination that never existed.
