## What it is
KAS is a pure-Rust GUI toolkit providing stateful widgets with automatic layout, theming, and accessibility support. It aims to make simple UIs easy to build while allowing complex custom widgets, producing fast monolithic binaries.

## Use cases
- build a desktop gui application in rust
- create cross-platform ui with stateful widgets
- make an accessible gui with keyboard navigation and screen reader support
- render complex text with bidi and font fallback in a rust app
- build a gui that compiles to wasm for the browser
- implement custom widgets with automatic layout and scaling

## When to choose
- you want a pure-Rust GUI toolkit without C/C++ bindings
- you need stateful widgets, automatic layout, and pixel-perfect scaling
- accessibility (keyboard, screen readers) and complex text support matter
- you want fast, monolithic binaries or wasm targets

## When to avoid
- you need a mature, battle-tested toolkit with a large widget ecosystem
- you need integrated internationalization support (not yet implemented)
- you prefer immediate-mode or declarative web-style UI paradigms
- you need mobile platform support

## Facets
- artifact type: library
- maturity: active
- function: gui, ui-components, graphics
- domain: desktop-applications, cross-platform, web-development
- platform: rust, cross-platform, wasm
- tags: gui-toolkit, stateful-widgets, pure-rust, accessibility, text-rendering, themes, desktop
