zwitschi 52e9cc80a8 fix(street): grade crossing ramps to <=8%; report step location in the pre-check
- kerb_height ramp run now derives from --max-ramp-grade (default 8%), giving
  1.63 m instead of the fixed 1.5 m (8.7%). Crossing route measures 3.4 cm at
  0.25 m sampling.
- site_assembly pre-check: coverage is independent of --sample (it used to shrink
  the route), and it now prints the grade and the s/offset location of the worst
  step so a step can be located instead of guessed.
- Documents the remaining south s=198 / north s=251 strip discontinuity as a
  finding on the 'audit collision gaps' item rather than claiming it fixed.
- Street + site rebuilt, site re-imported (7/7), DemoMap rebuilt; packaged
  -qaselftest PASS.

zwitschi bc2e421d33 gameplay: designated street crossing — zebra markings, corridor cut, up-facing street
- street_mesh.py: continental zebra markings (0.5 m bars, 0.5 m gaps, 3 m
  band) at all three signalised crossings, triangles not quads (FBX SDK
  refuses to triangulate the crown-twisted quads), stripes +6 cm above the
  DEM so they stay above the road surface; winding flipped so every street
  surface faces up (road/sidewalks/markings were 100% down-facing and
  invisible in engine once the terrain stopped covering them).
- terrain_from_dem.py: cut a 10.7 m corridor around the Hollywood Blvd
  centreline so road, kerbs and sidewalks are not buried under the terrain;
  sidewalks themselves cover the transition band, walk-check stays at 0 holes.
- Blender builders save with a writability guard + fatal failure: *.blend
  is LFS-lockable and checks out read-only; a failed save previously left
  downstream steps building from stale files.
- ue_import_site.py: Crossing_Markings imports with no collision (paint on
  the road); ue_build_demo_map.py stages it and chmods the lockable .umap
  before saving (save_map silently returned False on read-only maps).
- ue_build_review_map.py: demo-crossing camera moved to the real crossing
  (s=130.1 m -> UE -24291,-1340) and fixed the ensure_writable path (was
  missing the .umap suffix, so the chmod never fired).

zwitschi 386d4bee78 geo: one tool directory, one unit boundary, per-asset provenance
Geo/tools/ is now every geographic script, with Geo/README.md documenting each
one; the Blender-side builders moved beside their outputs in Art/blender/*/ and
import their helpers from Geo/tools/osm_common.py.

That module gains to_unreal_local() and to_blender_local(): the only place in the
repository that multiplies metres by 100, so a second silent scale cannot be
introduced. block_height_report.py adds height provenance for the block — 3 of
15 buildings have no height data and render at a placeholder 6.4 m.
asset_metadata.py writes and audits <asset>.geo.json sidecars; four now exist
(hero-facade, terrain, street, blockout) and the audit recomputes each centre from
the origin, failing anything that disagrees.
