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%.

+## `0.1.0` — Placement vs references — record (2026-11-08)
+
+Checked against the reference photography (`Art/reference/`) and the Geo measurements
+(`Geo/verification/*`). Build under test: current `main` content, DemoMap rendered via
+`Tools/render_screenshots.sh` (2026-11-08, Vulkan SM5, 1920×1080); engine positions
+probed from the DemoMap (commandlet, 2026-11-08).

+| South sidewalk strip | 7.3 m (bbox incl. kerb apron); built walkable strip 4.0 m per `Art/blender/README.md` | 12.6 m centreline offset; strip width from setback arithmetic | ✓ offset 12.5 m ≈ ref 12.6 m |

+
+| Shot | Reference(s) used | Verdict | Notes |
+| --- | --- | --- | --- |
+| `review-demo-spawn-view` | `hollywood/el-capitan-facade-day-*` (CC BY 2.0), `el-capitan-entrance/*` | PASS | Facade frontage, column rhythm and neighbour massing match; camera frames the whole block from the north sidewalk. |
+| `review-demo-street-level` | `hollywood/el-capitan-theatre-blade-sign-*`, `premiere-staging-*` | PASS | Street-level colonnade + frontage neighbours; sidewalk depth consistent with the blade-sign frame. |
+| `review-demo-crossing` | street-profile crossing s=130.1 m | PASS | Zebra markings visible along the crosswalk; kerb flushed at the crossing. |
+| `review-demo-north-buildings` | north-side OSM positions; TCL/Tussaud's `Art/reference/north-*` | PASS | Camera re-pointed 2026-11-08 (was 9.5 km west → 85% sky); buildings now framed. Flat blockout surfaces are the `0.1.4` scope. |
+
+### Deliberate deviations recorded
+
+- **North/south building surfaces are flat blockouts** (bloblike, no façade detail). Detail texturing/façade style is the planned `0.1.4` (Proper building façades) work; placement and massing are what this check verifies.
+- **Kerb upstand 0.13 m as built vs 0.15 m assumed**; the DEM cannot resolve a kerb — tracked in `0.1.1` (Kerb height assumption).
+- **Sidewalk surface detail** (railings, pavers, domes) not modelled — outside `0.1.0` scope.
+- **Crossing ramps are kerb flushes, not graded ramps** — the `0.1.1` Crossing ramp gradient item.
+- Site identity (the neoclassical hero with motto band) matches the 2009 façade photograph and the 1922 Masonic elevation within blockout fidelity.
+
+Pre-check method: `Tools/judge_screenshot.py` (vision model) flagged the simplified
+flat surfaces as "unexpected" — those flags are the deliberate deviations above, not
+placement errors. Final verdict is by human review of the shots in `Screenshots/demo/`.
