/* 本地自托管字体（替代 Google Fonts，零跨域阻塞）
 *
 * 俄语站字体策略：
 *  - 拉丁字符：沿用英文站原文件，保证与英文站观感一致
 *  - 西里尔字符：Barlow Condensed 官方没有任何西里尔字形，无法渲染俄语，
 *    因此标题的西里尔用同风格窄体 Roboto Condensed 顶替；
 *    正文 IBM Plex Sans 官方有西里尔子集，直接补齐，字体族不变。
 *
 * 实现方式：所有 @font-face 都声明 unicode-range，拉丁与西里尔互不干扰，
 * 页面 CSS 里的 font-family 无需改动即可正确分流。
 * 西里尔文件按需下载：纯拉丁内容不会额外请求西里尔字体。
