Imports not recognized in IDE ("Btn", etc.)

Hi, I'm wondering if there is a way to get Pylance / other IDEs' Python support to understand the dynamic types:

I think this doesn't happen in FastHTML proper because there are stubs. Will there be stubs in this library at some point, or is there a good way to generate them?

The issue names no files, tests, or entry points. Start by inspecting how the library defines dynamic types and imports, then compare that behavior with FastHTML's existing stubs and Pylance's expectations. Done means establishing whether stubs or a generation path should be added and confirming that imports such as Btn are recognized by Python IDE tooling.
