/* ---------------- 字体（轻量化：仅保留拉丁字形 Poppins 4 档） ----------------
 * 优化说明：
 *  1) 移除 AlibabaPuHui 4 个 TTF（合计约 32MB）。中文字形改用系统字体栈
 *     （PingFang SC / Microsoft YaHei / Noto Sans SC），零下载、渲染更快、
 *     视觉差异极小；原方案首屏需拉取 8MB+ 字体，是最大的性能瓶颈。
 *  2) Poppins 由 9 档精简为 4 档（400/500/600/700），其余字重由浏览器
 *     合成，体积从 1.4MB 降至约 620KB。
