/* 字体加载的防抖动策略（两层）。
   第一层：普惠体用 font-display:optional —— 字体没有赶上首帧就整页沿用系统字体，
   本轮不再替换，从机制上杜绝「文字重排把下方内容推走」。
   第二层：下面这个校准过的兜底字体，用于 optional 未命中时的系统字体渲染。
   实测系统字体比普惠体宽约 2.5%~2.7%：首页 h1 首行普惠体 597px（容器 613px，一行放下），
   换到系统字体是 612.75~614.36px，只差 1~2px 就折成两行，hero 会高 73px。
   按 96.5% 缩放后系统字体略窄于普惠体，保证这一行始终是 1 行。
   注意：全站 line-height 均为固定倍数（body 1.7 / 标题 1.28），
   缩放只影响字宽，不改变行盒高度，不会反向引入垂直抖动。 */
