qa(placement): record release-check 2 evidence + fix north-buildings camera

- Probed DemoMap world-space positions (commandlet) and compared against Geo
  reference measurements: road 24.3 m (ref crossings 20.9-25.9), sidewalk
  centreline offsets 12.5/13.2 m (ref 12.6/13.6), hero frontage 26.0 m and
  setback ~13 m (ref 25.75 m / 14.5 m), frontage + north buildings in verified
  OSM positions. Recorded as PASS with deliberate deviations (flat blockout
  surfaces -> 0.1.4; kerb upstand -> 0.1.1; kerb-flush crossing ramps -> 0.1.1)
  in Docs/release-checks.md.
- Fixed the demo-north-buildings camera: it sat at X -22800 (9.5 km west of the
  site) aiming at its own position -> 85%-sky frame. Now at the buildings' mass
  centre (X -22750) south of the road looking north; sky fraction 85% -> 41%.
