 * ===========================================================================
 * 应急小达人 v1.1.0 — 液态玻璃 + 3D 沉浸系统
 * ===========================================================================
 * 
 * 【模块说明】
 * v5-glass-3d.css 是游戏的核心视觉增强样式表，
 * 实现了苹果风格的液态玻璃(Glassmorphism)效果和 3D 透视交互。
 * 
 * 【设计灵感】
 * 参考 Apple iOS 26+ Liquid Glass 设计语言：
 * - 毛玻璃模糊背景 (backdrop-filter: blur)
 * - 半透明渐变边框
 * - 内发光高光效果 (inset box-shadow)
 * - 微妙的光泽反射 (::before 伪元素)
 * 
 * 【核心样式类】
 * 1. 液态玻璃核心材质
 *    - .quiz-opt, .scenario-opt: 答题选项玻璃卡片
 *    - .quiz-card, .scenario-card: 题目/情景卡片
 *    - .mode-btn: 模式选择按钮
 *    - .survival-hud: 生存模式 HUD
 * 
 * 2. 3D 透视效果
 *    - transform-style: preserve-3d
 *    - perspective: 1000px
 *    - rotateX/Y + translateZ 组合
 * 
 * 3. 动画系统
 *    - @keyframes glassShimmer: 玻璃光泽扫过
 *    - @keyframes float3D: 3D 悬浮漂浮
 *    - @keyframes neonPulse: 霓虹脉冲发光
 * 
 * 4. 交互状态
 *    - :hover 3D 倾斜 + 光晕增强
 *    - :active 按下缩放反馈
 *    - .active 选中状态高亮
 * 
 * 【浏览器兼容】
 * - backdrop-filter: -webkit- 前缀兼容 Safari
 * - 降级方案: 不支持时回退到半透明背景
 * 
 * 【性能优化】
 * - 使用 will-change 提示浏览器优化渲染
 * - 限制 blur 半径在 20-30px 范围内
 * - 避免在动画元素上使用 backdrop-filter
 * 
 * @version 5.0 (glass-3d-unified)
 * @date 2026-06-05
