/* 专题详情页（topic-page.js，第 4 轮 Part T2）的样式：作用域为 .topic-page > .page-head、.topic-page-tabs 与 .topic-tab-{overview,materials,reports,notes,settings}。
   版式取设计稿 e-formal 的“文件”语言（与今日、研究专题列表同一套）：白色纸面、细线分隔、左侧 88px 标签栏（--ss-report-label）+ 正文栏，
   宋体（--ss-font-serif）只用于标题与关键数字；声纳青只用于链接、引用、选中状态与新内容；每屏一个主按钮；用细线，不用卡片。
   页头带的几何与页签的窄屏滚动、渐隐沿用 formal-theme.css（.page-head.report-head、.tabs.deep-tabs，规格 23.41），这里只改字体、颜色、标签与页签计数。
   概览栅格同今日：≥1280px 正文 + 380px 右栏（间距 48）；1101–1279px 右栏 320（间距 40）；≤1100px 单栏、“专题概况”在正文之后。
   断点 1280 / 1100 / 800 / 480；颜色只用 var(--ss-*) 令牌或其 color-mix（深色主题随令牌切换）；不用 !important，不写内联样式；
   作用域内的 [hidden] 一律不显示（作者样式的 display 会盖过浏览器默认的 [hidden]）；强制配色、打印与减少动态效果各有对应规则。 */
