   🔴 本文件必须保持为**外部样式表**，不得改回页面内联 <style>：
      站点 nginx 下发 Content-Security-Policy: default-src 'self'（未开放
      style-src 'unsafe-inline'），浏览器会**静默丢弃**内联 <style> 块与
      style="..." 属性 ⇒ 本页原来整块样式失效、页面裸奔。
      本文件内容逐字取自原页内联 <style> 块（仅去掉公共缩进），并收纳原本写在
      标签上的内联样式（见文件末尾的 .announce-main / .qr-image / ... 规则）。
