geo: measure the block street profile and fix the local CRS and origin

New Geo/scripts/street_profile.py measures the 279.4 m block centreline, the
three signalised crossings (20.9-25.9 m across), sidewalk centrelines at 12.6 m
and 13.6 m, and per-building setbacks of 13.0-15.8 m. Derived sidewalk widths
of ~4.0 m south and ~5.3 m north cross-check against the mapped centrelines.

Geo/manifests/local-origin.md fixes EPSG:26911 and the Highland intersection
node as origin, defines the axes and the x100 metre-to-centimetre rule, and
leaves the projected pair blank because PROJ is not installed here.

Records the lane-count discrepancy (4 tagged lanes over a 20.9 m carriageway).

-- **Pavement and roadway widths.** The extract carries no sidewalk or carriageway widths. Needed for the walkable demo, the crossing, and street scale against the reference photos.
-- **Crossing location.** No marked crossing geometry confirmed yet, and `0.1.0` requires one designated crossing.
 - **Elevation.** No DEM checked. The choice between using a separately licensed DEM and skipping it depends on measured height variation across the 279 m block.
-- **North-side reference photography.** Both north-side buildings are in scope and neither appears in the reference set. They cannot be detailed from evidence yet.
 - **Façade width conflict.** 29.6 m from the sibling project's venue notes against the 25.7 m OSM bbox; recorded in [`../../Docs/reference-notes-hollywood.md`](../../Docs/reference-notes-hollywood.md) and unresolved.
+- **Projected origin value.** The CRS and origin point are fixed in [`../manifests/local-origin.md`](../manifests/local-origin.md); the EPSG:26911 easting/northing still needs computing with PROJ or QGIS.
 
-Next: measure roadway and sidewalk widths, fix the local CRS and origin, and resolve the façade-width conflict before any façade modelling.
+Measured since this pass: street profile, carriageway and sidewalk widths, and the designated crossing — see [`2026-11-06-street-profile.md`](2026-11-06-street-profile.md). North-side reference photography was fetched on 2026-11-06 (local only); see [`../../Docs/reference-notes-hollywood.md`](../../Docs/reference-notes-hollywood.md).

+Next: settle the façade width, check elevation, and complete the projected origin, then the Blender blockout can start.
