I don’t want to be a curmudgeon, but why not just use CSS, HTML, React, etc. at this point? You could choose a style that looks like a TUI.

But will it render in a terminal over ssh?

(I know, I know, port forwarding should work for a web app.)

It actually will given the excellent quality of text based browsers now.

		Agreed. Another thing that gives the TUI concept an edge is the lack of formatting options: no way to make a font too tiny or too huge, very little leeway in implementing common controls, any excessive whitespace looks jarring, etc. Icons are limited to the common emoji. All this makes you concentrate on providing functionality first.
