# Expressway grand tourer

Original portfolio coachwork developed from the approved `../evolution/nightdrive-evolution.blend` at `c9ac36e`. No third-party model, texture, or generated project evidence is used.

- `nightdrive-expressway.blend`: isolated editable source. Open the **Midnight Expressway** scene. Body components, optical cells, intake vanes, wheel machining, panel seams, wing details, and look-development setup remain editable.
- `author-expressway.py`: appends the approved source into a separate scene and authors this edition. Run once in a fresh Blender session with `__file__` set to the script path. It saves only the isolated expressway library; it does not overwrite the approved evolution source.
- `export-expressway.py`: run with the expressway source open. It evaluates modifiers into a separate export scene, batches by material and wheel, exports the runtime GLB, and writes its provenance JSON. Four wheel parents remain independently rotatable. Cameras and look-development lights are excluded.
- `nightdrive-expressway.asset.json`: export path, SHA-256, triangle count, and source lineage.

Runtime: 31,288 triangles, 19 material batches, four independently rotating wheel groups. Geometry follows the existing Blender-to-glTF coordinate convention and runtime scale. Body suspension is applied separately from grounded wheels.

The runtime asset is `src/assets/nightdrive-grand-tourer-expressway.glb`. The review contains a Blender look-development render and actual in-browser views. The Static-mode JPEGs are captures of this portfolio's live Three.js world; they contain no fabricated project media.
