/* ---------- 矮视口兜底（手机横屏 / 低分辨率矮屏）----------
   只按宽度做断点认不出横屏手机：iPhone 横屏宽 812px > 768px，会被判定为桌面，
   于是套上三行固定页眉（153px）——在仅 375px 高的屏幕上吃掉 37% 可视区，
   且 hero 取 min-height:100vh、标语字号按 8vw 冲到 64px 上限，完全不成比例。
   这里按「视口高度」再兜一层，不删减任何内容：
     · 页眉改为随文档滚动，把高度还给正文（品牌/释义/资质/导航全部保留）
     · 压缩首屏 hero 上下留白，并让标题字号同时受视口高度约束
   实测：812×375 页眉占屏 37% → 修复后降到 0（不再固定，随页面滚走） */
