Third-party notice

This project's own source is under the MIT License above. It ships one generated
file, `lib/client.vendor.js`, which bundles other MIT-licensed software:

  * three.js                (c) 2010-2025 three.js authors      MIT
  * @pixiv/three-vrm        (c) pixiv Inc.                      MIT
  * @pixiv/three-vrm-animation (c) pixiv Inc.                   MIT

(@moeru/three-mmd and mmd-parser were bundled until 2026-10-12, when this project
became VRM-only and the MMD stack left both the chunk and `vendor/package.json`.)

Their license texts are preserved inline in that file's banner and comments.

It also ships ONE 3D model file, `assets/models/SampleModel.vrm`, whose own
embedded metadata allows redistribution, modification and commercial use with no
attribution required — see `assets/models/README.md`, and `check-docs.mjs` asserts
those terms on the committed bytes. Every other model is supplied by the user and
remains under its own author's terms.
