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).
Gig Line
A Linux-first Unreal Engine game about walking and driving through a real city. The first release, 0.1.0, is a walkable exterior demo around 6840 Hollywood Blvd / El Capitan Entertainment Centre, covering the south-side frontage between Highland Avenue and Orange Drive plus the north-side frontage within 50 m of the boulevard.
Status
Pre-production. Workstation setup and repository scaffolding are in progress; no engine, content, or geographic data is committed yet. Current state is tracked in ROADMAP.md, and the per-task setup state in Docs/setup.md.

Getting started
git lfs install # required: content, images, audio, and geo files are LFS-tracked
git lfs pull
Tools/check-lfs.sh # verifies the lfs filter is active and files are stored as pointers
The engine is installed outside the repository and pinned in Docs/toolchain.md. The full procedure is in Docs/setup.md.
