Animation

Topic	Start here
Animation intro	https://docs.blender.org/manual/en/4.5/animation/introduction.html

Export for Twin (glTF / GLB)

Topic	Start here
glTF 2.0 add-on (4.5)	https://docs.blender.org/manual/en/4.5/addons/import_export/scene_gltf2.html
glTF 2.0 add-on source and docs (Khronos)	https://github.com/KhronosGroup/glTF-Blender-IO

Checklist:

1. Apply transforms where needed
2. UV + Principled materials ready
3. Animation = active Action / NLA as required by exporter
4. Export glTF Binary (.glb) for Bitstream / Twin webview
5. Compare naming with ternion-3d-assets-free models
