Description

This is a well known pyscript pattern; it allows for the UI to load very quickly (because micropython is small) while pyodide loads in the background.

This is probably not an easy task because it requires a lot of pyscript experience. Unfortunately I cannot find any docs or tutorial for how to use this pattern.

Contributor guide

Research direction
Study the pyscript pattern for using micropython for UI and pyodide in a worker. Look for examples in the pyscript community or similar projects. Understand how to load micropython quickly and then transition to pyodide for full Python capabilities. Consider the spy language's architecture and how to integrate this pattern.
