 * ========== Inter 字体配置 - 中文优化版 ==========
 *
 * 文件说明：Inter 字体族配置，针对中文显示进行优化
 * 维护说明：移除了不适合中文的过粗和过细字体权重
 *
 * ========== 字体权重说明 ==========
 *
 * 1. 保留的字体权重（适合中文显示）：
 *    - 300 (Light): 轻量级，适合辅助文本
 *    - 400 (Regular): 常规，适合正文内容
 *    - 500 (Medium): 中等，适合强调文本
 *    - 600 (SemiBold): 半粗体，适合标题
 *    - 700 (Bold): 粗体，适合重要标题
 *    - 900 (Black): 超粗体，适合高桥流汇报体设计
 *
 * 2. 移除的字体权重（不适合中文）：
 *    - 100 (Thin): 过细，中文字符显示不清晰
 *    - 200 (ExtraLight): 过细，中文字符显示不清晰
 *    - 800 (ExtraBold): 过粗，中文字符显示过于厚重
 *
 * 3. 字体族说明：
 *    - InterVariable: 可变字体，支持连续权重调整
 *    - Inter: 静态字体，用于兼容性
 *    - InterDisplay: 显示字体，用于大尺寸显示
 *
 * 4. 中文字体回退：
 *    - 优先使用 Inter 字体族
 *    - 中文字符回退到系统字体：PingFang SC, Hiragino Sans GB, Microsoft YaHei
 *
 * ========== 使用示例 ==========
 *
 * CSS 变量使用：
 * :root { font-family: "Inter", sans-serif; }
 * @supports (font-variation-settings: normal) {
 *   :root { font-family: "InterVariable", sans-serif; font-optical-sizing: auto; }
 * }
 *
 * 权重使用：
 * .text-light { font-weight: 300; }
 * .text-normal { font-weight: 400; }
 * .text-medium { font-weight: 500; }
 * .text-semibold { font-weight: 600; }
 * .text-bold { font-weight: 700; }
 * .text-black { font-weight: 900; }
