# Chromatic grand tourer

Original paint edition of the approved expressway coachwork at `43e5103`, descended from the evolution model at `c9ac36e`. No external models or textures are used.

- `nightdrive-chromatic.blend`: isolated **Chromatic Nightdrive** scene with editable geometry, rose and violet layered paint, sapphire glass, champagne wheel machining, and look-development lights.
- `author-chromatic.py`: appends the approved expressway source and changes its materials in an isolated scene. Set `__file__` to this script when executing in Blender. It writes only the chromatic library.
- `export-chromatic.py`: run with the chromatic scene loaded. Evaluates modifiers and batches by material and wheel, retaining four independently rotatable wheel parents. Writes the GLB and SHA-256 provenance.
- `nightdrive-chromatic.asset.json`: source lineage and export statistics.

Geometry is unchanged: 31,288 triangles and 19 material batches. Runtime studio reflections supply cool edge light and a rose rim over the exported enamel. Runtime emissive fill remains subtle; the body is lit paint, not an illuminated surface. The earlier Blender sources and exports are preserved.

The chromatic Static-mode JPEGs are direct captures of this portfolio’s runtime world at desktop and phone sizes. They contain no project evidence or invented imagery.
