What is SUS?

SUS UI is a reactive UI framework for Unity UI Toolkit, inspired by Vue.

Pillars

1. Reactivity — Prop<T>, Computed<T>, Watch — change data, DOM updates.
2. .sharq SFC — single-file components: <template> + <script> + <style>.
3. Component library — SusKit (general UI) + SusGame (HUD / inventory / screens).
4. Router — Vue Router-like navigation for screens and modals.
5. Theming — design tokens, density, breakpoints, world-space overlays.

Mental model

If you know Vue SFCs, you already know the shape of .sharq:

Vue	SUS
props	Prop<T> (use .Value)
v-if / :class	same directives
<slot>	<slot>
watch	Watch / WatchEffect
Vue Router	SusRouter
