GLB Scaling Animation Needed

I have an existing GLB model that needs a clean, lightweight scaling animation baked in. The brief is straightforward:

• Primary action: object transformation—specifically scaling.
• Behaviour: it must play in a seamless continuous loop and also be able to start or stop when called by an external event (so the file ships with both versions or a single file that supports both behaviours through animation tracks).

Please deliver the final GLB with the animation embedded, ready for web viewers (Three-js, babylon.js, etc.) and standard 3D apps. If you work in Blender, Maya or similar, that’s fine—just ensure the exported glTF 2.0 file retains proper animation channels and naming so developers can trigger them easily.

Let me know your preferred workflow and how soon you can turn this around along with any questions about the model.
