Three.js local bundle (required)

To pass WordPress.org Plugin Check, this plugin must load Three.js from local files (no CDNs).

Place the following files here:

- assets/three/build/three.min.js
- assets/three/examples/js/controls/OrbitControls.js   (optional)
- assets/three/examples/js/loaders/GLTFLoader.js      (optional)

You can obtain these from the official Three.js release package:
https://github.com/mrdoob/three.js/releases

After adding the files, the admin Live Preview and frontend shortcodes will render correctly.
