Could you build this?

Partial Generating standard Ruby wrapper code is straightforward, but creating robust FFI/C-extension bindings to an active Rust TUI library (Ratatui) while managing terminal event loops and memory across language runtimes requires systems expertise.

What it would actually take: The library involves writing Ruby C extensions or FFI/Magnus wrappers in Rust around Ratatui and `crossterm`. The hardest parts are cross-language memory management, coordinating non-blocking terminal event polling across the Ruby GVL (Global VM Lock), and safely mapping complex Rust traits/widgets into idiomatic Ruby objects. This requires specialized knowledge in C/Rust ABI interoperability and Ruby internals.
