Could you build this?
Partial While presenting a demo in HTML/JS is straightforward, porting and rendering a full-fledged high-performance terminal UI emulator with custom font rendering, layout engine, and terminal semantics to WebAssembly/Canvas is nontrivial.
What it would actually take: The underlying architecture requires a terminal engine written in Rust or C compiled to WebAssembly, drawing to an HTML5 Canvas or WebGL context. It must handle VT100/xterm escape sequence parsing, custom monospaced glyph rasterization, and precise cursor/selection states. A systems/graphics engineer experienced in WebAssembly and terminal emulators is needed for the core rendering layer.
