/* ═══ 2026-09-11 修复：1240–1682px 导航溢出（登录入口/主 CTA/币种被裁）═══

/* ═══════════════════════════════════════════════════════════
   2026-09-11 fontfix1：全站文本输入控件 ≥16px（iOS 聚焦防缩放）
   ═══════════════════════════════════════════════════════════
   取证：font-scan.cjs 实测 11 页 77 个控件，46 个 <16px（其中 17 个可见，
   会真实触发 Safari 聚焦放大）。上方 239 行 Wave-0 先例只覆盖
   .th-nav-search / .th-nav-track-form 两个选择器，其余控件全部漏网：
     首页 #productLink 14.40px ／ /expert/ 表单 15.20px
     /account/ .tf 14.08px ／ 币种 select 11.52px(静态页) 10.51px(WP页)
     /cart/ /faq/ /about-us/ 站头搜索 14.59px ／ #thChatIn 13.60px
   做法：th-nav.css 是全站最后加载的公共样式表（静态页 ?v= ／ WP 页
   wp_enqueue_style ?ver=），在此统一兜底 —— 一处覆盖全站。
   排除 button/submit/reset/checkbox/radio/image/range/file：它们不唤起
   键盘、不触发缩放，强改字号只会破坏按钮版式（全站实测 37 个
   type="button" + 3 个 type="submit"）。
   ⚠️ 仅窄屏/触屏生效，桌面端不受影响。 */
