/* 几策 · 视觉精修层（全站最后加载，统一收口）
   ------------------------------------------------------------------
   目标：把「模板感 / 廉价感」的来源统一处理掉，让三套主题都能保持
   简洁、克制、有质感：

   1. 只消费语义 token（--color-* / --text-* / --radius-* / --shadow-*），
      不写死任何色值，保证三套主题（星穹 / 玄墨 / 霁光）一次改完同时生效；
   2. 排版：统一字体族、字号阶、字重（标题 600 而非 700/900）、字距、行高；
   3. 材质：卡片实色 + 1px 细线 + 中性阴影，去掉彩色外发光、渐变描边、
      流光按钮、扫描线一类的装饰噪点；
   4. 圆角收敛到一套（控件 8 / 卡片 14 / 面板 16），避免同页多种圆角打架。

   选择器统一带 html.xt-v2 前缀（由 theme-boot.js 在解析 CSS 前挂上），
   与旧层同特异性但更靠后加载，因此无需堆砌 !important 也能稳定覆盖。 */
