/* ============================================================
   博客前台门户样式（独立于管理端；仅依赖 layui 按钮/表单基础样式）

   设计口径（60-30-10）：
   - 60% 主色：页面背景（亮 #fafafa / 暗 #16181d）
   - 30% 辅助色：卡片/头部表面色（surface）
   - 10% 点缀色：accent（按钮/链接/高亮，亮 #16b777 / 暗 #3ecf9a）
   - 主题：html[data-theme=dark] 切换，变量集中在 :root 与 [data-theme=dark]
   - 排版：系统字体栈（sans + 等宽两种），正文 15px / 1.75，标题层级显著
   - 动效：悬停轻浮 + 阴影、卡片入场淡入，克制不抢戏
