Since the page is already deployed on GitHub, I think we can just fetch the YAML file from there instead of hardcoding it locally.

Yes, you are right about it.
But there is a problem:
We often update the API before updating the backend implementation.

I think we can discuss how to control the API version so we keep track of the API spec of the backend version.
