A: Hello, sorry for my late answer.
The practical difference between export "Screen" and "Codebase + Screen" is mainly about the scope of what's exported:

Export "Screen": This only exports individual screens one by one. It's useful when you just need to share or work on a specific part of the project, without the full logic or dependencies behind it.

Export "Codebase + Screen": This exports the entire project, including all screens and the underlying codebase (logic, structure, and possibly reusable components). It's designed for full project handoff or more advanced development workflows.

The first version of Codebase + Screen exports everything (all screens + full code), but it's going to evolve with more modular export options, meaning you'll be able to pick and choose what parts you want to include in the future.
