/* ---------- 内页 hero 背景图的窄屏裁剪锚点 ----------
   `.page-hero-media img` 用的是 object-fit:cover，而这几张源图是 3:1 ~ 3.3:1 的
   超宽横幅，手机端 hero 容器却只有约 1.1:1。按默认的 object-position:50% 50%
   居中裁剪，375px 下只能显示源图约 33% 的宽度 —— 主体若偏在一侧就会被整个裁出画面。
   下面按每张图**实测的主体位置**（canvas 逐列对比度分析）设定窄屏锚点。 */
  /* hero-goldbars.jpg（1920×575, 3.34:1，quote / mall 两个页头共用）：
     金条主体位于源图 70%~81%，其余 60% 是空白渐变背景。
     默认 object-position:50% 50% 在窄屏下只露出源图中间 3 成宽度（375px 时
     x33%~67%），金条被整个裁掉，页头只剩一片空白 —— 实测确认过。
     锚点取 78%（不取 100%）：让金条稳定落在视口右侧 54%~87%，
     保住桌面端「左文右图」的构图，也不会把金条压到标题文字正下方。
     注意这里**不加媒体查询**：宽屏时可见窗口已接近整图，78% 与 50% 只差约 16px
     （肉眼无差别），但一旦收窄就立刻起到保护作用，比卡断点更稳。 */

   导航折叠补丁 —— 必须放在文件最末尾
   -------------------------------------------------------------
   原因：.nav-intl 的基础规则在「20260915 导航改版」段落（文件靠下）定义，
   与折叠规则同为【单类选择器】时，按源码顺序取胜。
   把 .nav-intl{display:none} 写在基础规则之上会被
   .nav-intl{display:inline-flex} 覆盖 —— 实测表现为 320px 小屏下
   「粤鑫国际」按钮（宽 150~207px）把汉堡按钮顶出视口 43px。
