Build me a lightweight front end framework for React that makes Redux and async data flow feel much simpler.

I want it to be easy to use, with a small set of APIs, and the main way to organize app logic should be models with reducers, effects, and subscriptions. It should work nicely with routing, support hot reloading for components, routes, and models, and have a plugin system so things like loading state can be handled automatically.

Please set up the core library, a few clear examples, and basic docs that show how to get started and how the main concepts fit together. If you need to check the latest docs for any related tools, look them up online.

The result should feel like a practical framework someone could use to build dashboards or other real apps, not just a toy demo.
