/* =====================================================================
 * ②号子屏幕 · 相册组件（Char 自拍相册）独立样式
 * ---------------------------------------------------------------------
 * 风格：Korean Minimal（韩式极简）× Vertical Timeline（垂直时间线）
 *   - 主背景 暖白 #faf9f7 / 主文本 石板蓝 #3d4a5c / 点缀 粉彩 #d4a5a5、#a8c5b8
 *   - 极细边框(1px, 低透明度) + 柔和阴影 + 大圆角 + 轻盈字重 + 留白呼吸感
 * 布局：相册主界面为垂直时间轴——左侧连接线串联「按天分组」节点，
 *       每组卡片区同排最多两张照片，卡片下方展示照片来源与保存时间。
 * 入口外观：磨砂玻璃唱片套 + 圆形封面窗 + 右侧黑色胶片（黑色部分恒定）。
 * 主题：随 --lmg-* 与暗色联动；黑色胶片恒为黑。
 * 兼容：iOS Safari / 安卓各厂商浏览器（华为、小米、OPPO、魅族、vivo、三星）
 *       与 Via、夸克、雨见、搜狗等：safe-area、-webkit- 前缀、backdrop-filter
 *       与 aspect-ratio 均有兜底；动画遵循 prefers-reduced-motion。
 * 命名：统一 ss2ab- 前缀，独立文件，不与其它屏幕/组件共用。
 * ===================================================================== */
