This is such a cursed combination... I really don't understand what you get from Godot that benefits you for building a TTY "multiplexer."

Wildly vibe-coded to the extent that it's more misguided than Doom on a pregnancy test...

Also looking at OP's notes here, there doesn't even seem to be a need for this to exist, "FPS counter" ..? Perhaps, I don't know, fake terminals on a spaceship or something. Yueash...
