   APEXAI 新闻中心 —— 列表页 / 详情页专用样式
   仅由 news/index.html 与新闻详情页引用，不参与站点其余页面加载。

   说明：
   1. 头部、导航、页脚统一复用站点 header.html / footer.html，样式来自 css.css
      与 media.css，此文件不再重复定义，避免与站点同名选择器互相覆盖。
   2. 断点与站点保持一致：1200 / 1240 / 900 / 600。
   3. body 的上边距、字体、全局重置由 css.css 负责，此处不再声明。

/* 字体链修正
   ------------------------------------------------------------------
   站点 css.css 里写的是 * { font-family: HarmonyOS_Sans_SC }，而系统实际安装的
   字体族名是 HarmonyOS_Sans_SC_Regular / HarmonyOS_Sans_SC_Bold，两者不匹配，
   等于没有声明字体链，于是整页由浏览器回退字体渲染；粗体标题会回退到
   Microsoft YaHei 的 Bold 字面，而该字面缺少 U+00B7「·」字形，标题里的
   分隔点就会显示成方块（正文用的是常规字重，所以不受影响）。

   这里为新闻页显式声明一条能命中的字体链，并把实际含有 U+00B7 字形的字体
   （HarmonyOS / Arial 等）排在 Microsoft YaHei 之前，保证分隔点正常显示。 */
