/* ============================================
   飞越山海智能体定制空间站 — 首页品牌重构 v7
   v7关键修复：
   1. guofeng.css的黑金渐变 -webkit-text-fill-color:transparent 是
      "只能看清上半部"的元凶（渐变中段纯黑在深底上不可见）→ 强制重置
   2. h1/em/span统一重置 background-clip 和 text-fill-color
   3. 纯色亮金 + 锐利深色阴影，清晰亮眼不发虚
   4. 衬线字体增强国风味，nowrap防折行
   v6修复（保留）：.hero backdrop-filter:none 关闭父级模糊
