   v=37 终极方案：Courier New 等宽字体 + 标签高度锁死 30px
   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
   关键改动：
   1. 数字方框（.pc-postal-input / .pp-digit / .sc-pc-postal-digit）
      统一 Courier New 等宽字体（v=v=36 用 Arial tabular-nums 失败）
   2. 三套样式合并：用通用选择器一举统一，避免三处不同步
   3. label 高度锁死 30px，与 digit box 完全等高

   v=37 终极方案：数字方框换 Courier New 等宽字体 + 标签高度锁死
   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
   根本原因：html2canvas 1.4.1 对 Arial 渲染 "1" 时宽度计算异常，
   即使加 font-variant-numeric:tabular-nums 也无法可靠转化为等宽。
   "1"窄 "0"宽 → 同一 box 中数字视觉位置不一致 → 看起来"没对其"

   解决：用 Courier New 这种**本身就是等宽**的字体。
   每个数字占同位字符宽（如 8.4px），无论"0""1""3"都一致，
   → text-align:center 自动完美居中 → box 自然跟着数字走。
