Probe 22 points with the USGS 3DEP point service: walkable surfaces span 115.65-119.59 m, a 3.94 m relief, so elevation data is required by the AGENTS rule. Grade falls ~3.3 m eastward over the 279 m block (1.2%) and the north sidewalk sits 0.4-0.7 m above the south. 3DEP 1 m is public domain and becomes the chosen source; the tile itself is still to be downloaded. Factored the shared OSM helpers into Geo/scripts/osm_common.py so the street profile and the elevation probe read the same geometry.
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.
