Build me a fast Python web framework and server that feels simple to use, like a clean way to spin up APIs and web apps without a lot of setup.

I want it to support async and await, handle normal routes, return JSON easily, and run a tiny hello world app from the command line. It should be built for Python 3.10 or newer, work well as an ASGI app, and be focused on speed and non blocking requests. Make sure there is a straightforward way to create an app, register a route, and return a response. If you need to check current docs or patterns online to make the implementation solid, go ahead.

Please also include a small example app and enough tests to show the basic flow works, so I can see how to use it right away.
