Yes, it was two Svelte apps. One for the menus and one for the in game ui/hud elements. Things like health bars, reticles, ability timers, etc. The interface between the game engine was designed to be as decoupled as possible. The UI could run in a browser with a mocked game underneath it, which allowed the UI devs to iterate very quickly. This also has the advantage of allowing UI to be built before the game had a feature implemented.
