/* ============================================================
   灵犀日报 · 内容页（/daily · /bid）组件层
   ------------------------------------------------------------
   设计语言：延续订阅页的深蓝渐变 + 毛玻璃卡片，
             在此基础上叠加「数据管道」科技感：网格底纹、扫描线、
             等宽控制-label、管道式步骤条、大字号 monospace 指标。
   硬性约束：
   1) CSP 为 style-src 'self'，**不允许内联样式**，所以本文件必须外链；
   2) 明暗由 assets/theme-init.js 按本地时间自动切换（07:00–19:00 浅色），
      本文件用 html[data-theme="day"|"night"] 双向适配，不写死颜色；
   3) 所有动效在 prefers-reduced-motion 下必须停止。
