/* 低粉爆文榜 · 浅绿液态玻璃
   ────────────────────────────────────────────────────────────────
   材质沿用项目 liquid-glass.css 的三件套，不自造一套：
     ① background-image 斜向高光（绝不挂 ::after —— 伪元素画在文字之上会洗灰正文）
     ② background-color 白度 .73 打底（太低是毛玻璃糊，太高就不是玻璃）
     ③ backdrop-filter: blur(24px) saturate(165%)（24px 是实测值，过重会吃掉背景色场）
   边界分层：页头保持轻玻璃；概览、说明条和榜单行用低对比细线界定区域，
   控件保留清晰的功能边界。避免卡片套卡片，也避免把内容压成一整张白纸。

   配色在 #lowfans 作用域内定义，不污染全局 tokens —— 与 hotspots.css 同一做法。
