I like to take artifacts people are guaranteed to need and use them to represent architecture via introspection. Package files and manifests are enough to get you 80% of the way there, you can add annotations to package files and docstrings/doc comments to go as deep as you need. That keeps your architecture in Git and coupled to the code.
