`LeePerrySmith.glb` is the original 404,976-byte geometry asset. No textures or external asset scripts are used. Its embedded glTF data contains mesh/material data only.

Changes for Lichen: crop the chest to a short neck; taper shoulder width; derive anatomical surface sections; project smooth jaw/chin, cheek/muzzle, closed eye-socket/lid, brow, nose-bridge, nostril and lip guides onto the scan; decimate a separate silhouette mesh. The scan's actual facial anatomy is preserved. `lichen-head.blend` stores the modified surface and the 3D contour guides. The feature curves are exported separately from the lighter surface sections so facial anatomy has visual priority. The runtime uses `lib/playground/v2/head-contours.json`, rather than loading the modeling asset or Blender.

Reproduce from this repository root using Blender 5.2:

```sh
/Applications/Blender.app/Contents/MacOS/Blender --background --factory-startup --disable-autoexec --python scripts/build-lichen-head.py
```

This opens an isolated factory scene and never touches a running Blender instance. It imports the GLB as data, writes the scene and compact JSON, and produces front/quarter/profile clay inspection renders under ignored `review-artifacts/round1/`. No asset-embedded scripts are executed.
