/* 通用卡片 —— 液态玻璃（Liquid Glass 复刻手法）
 * 借鉴「contrast 对比增强 + 对角成对边缘光 + 内缘暗圈 + 斜向光带」：
 *  - 背景不透明度 ~0.05 + 1px 模糊，内容完整透出
 *  - inset 对角亮边（左上/右下）模拟光在玻璃边缘的折射聚光
 *  - inset 暗圈模拟玻璃厚度
 *  - ::before 斜向白色光带（45°）+ 顶部微光，模拟环境光反射
 *  - 外层 contrast 温和增强，放大边缘光晕（lensing 感）
 * 会变色：边缘光/高光跟随封面主色（--glass-rgb，见 glass.js）
