The lack of accessibility of TUIs is not great in general.

I'd much rather terminals emulator provide a webview directly, and maybe use https://webtui.ironclad.sh/ if you really want the look.

I think it makes more sense for a cli to offer a mini webserver instead.

Think `fish_config`, but opened in the terminal directly [0].
