/* ============================================================
 * DORO OPERATIONS · VPS Watch · 机房值班日志 —— 2026-09-30 重新设计
 * 延续原「暖纸手账」风格：纸张底纹、绿色书脊、牛皮纸胶带、红图钉、墨线与手写标题。
 * 新增：印章状态、铅笔排线进度条、机队心电图、巡检倒计时、滑动页签墨迹、
 *       卡片入场/状态变化动画、便利贴提示、抽屉交互趋势图。
 * 状态始终「颜色 + 图标 + 文字 + 线型」表达；prefers-reduced-motion 下关闭全部动效。
 * 素材：../img/*.webp|png，字体：../fonts/handwriting.css（Ma Shan Zheng）。
