@googlebot I signed it!

I have signed the CLA.

I noticed this branch is behind main — I'll update it shortly.

This guide documents a direct A2A-to-ADK bridge approach for integrating Google ADK agents with the A2UI web interface. It's based on a production implementation using FastAPI for protocol translation.

Happy to address any feedback or suggestions from the maintainers. Thanks for reviewing!

Branch updated and CLA check passed! Ready for workflow approval and review when you have a moment. Thanks!
