/* ==========================================================================
   招商轮船风险监测智能体 · 落地页主题
   CMES Risk Monitoring Agent — public landing page

   设计语言取自 2026 世界航商大会提案页（wmm/03 方案 B）：
   航海深蓝 + 天青 + 纸质浅色的交替段落、衬线标题配无衬线正文、
   1px 发丝线分隔、切角（chamfer）实心块、克制的动效。
   文案与图形均为本产品自有内容，未复用参照页的文字或影像。

   工程约束：
   - 零外部依赖（无 CDN、无外链字体、无外链 JS/CSS/图片/地图）。全部为系统字体栈。
   - 动效只动 transform / opacity；prefers-reduced-motion 全量降级。
   - 无 JS 时除登录卡外全部可读（正文不依赖 class 切换显隐）。
   - 色值不作为唯一语义载体：四级预警每一处色块旁边都有文字等级名。
