/* dailylog · 样式（Apple 官网风格）
 *
 * 设计语言要点：
 *   · 字体走 -apple-system / SF Pro + PingFang SC，标题负字距
 *   · 底色 #f5f5f7，卡片纯白无边框、大圆角、极淡阴影
 *   · 强调色 #0071e3（Apple Blue），链接 #0066cc
 *   · 按钮一律胶囊形（radius 980px），输入框灰底无边框 + focus 蓝色光晕
 *   · 顶栏毛玻璃：saturate(180%) blur(20px)
 *   · 缓动 cubic-bezier(.28,.11,.32,1)（Apple 官网同款）
