+/**
+ * @esengine/ui - ECS-based UI System
+ *
+ * 基于 ECS 架构的 UI 系统，支持 WebGL 渲染
+ * ECS-based UI system with WebGL rendering support
+ *
+ * @example
+ * ```typescript
+ * import { UIBuilder, UILayoutSystem, UIInputSystem, UIAnimationSystem } from '@esengine/ui';
+ *
+ * // 创建 UI Scene
+ * const uiScene = world.createScene('ui');
+ *
+ * // 添加 UI 系统
+ * uiScene.addSystem(new UILayoutSystem());
+ * uiScene.addSystem(new UIInputSystem());
+ * uiScene.addSystem(new UIAnimationSystem());
+ *
+ * // 使用 UIBuilder 创建元素
+ * const ui = new UIBuilder(uiScene);
+ *
+ * const button = ui.button({
+ *     x: 100, y: 100,
+ *     width: 120, height: 40,
+ *     label: 'Click Me',
+ *     onClick: () => console.log('Clicked!')
+ * });
+ *
+ * const progressBar = ui.progressBar({
+ *     x: 100, y: 160,
+ *     width: 200, height: 20,
+ *     value: 75,
+ *     maxValue: 100
+ * });
+ * ```
