/* ============================================================================
   飞鱼盾 FeiyuGuard · 页面设计层
   ============================================================================
   只在这些页面加载：
     /feiyu  /feiyu/pricing  /feiyu/docs  /feiyu/activate
     /feiyu/checkout  /feiyu/order/success
     /account/licenses  /account/license

   为什么要单独一层
   ------------------------------------------------------------
   app.css 是整站共用的（门户、产品页、下单作战板都在用），
   在里面加大改动会影响已有页面。所以飞鱼盾的视觉全部用 fg- 前缀
   写在这个文件里，只覆盖自己需要的部分。

   设计取舍
   ------------------------------------------------------------
   · 沿用站点的深色刻度（--bg / --surface / --sep / --label），
     不自造一套颜色，避免和别的页面割裂
   · 强调色只有 --accent 一支，用在 CTA、eyebrow、高亮卡片上；
     其余全靠亮度层级表达（深色模式下阴影看不见，靠亮度）
   · 间距用 8 的倍数，段落节奏 72-96px
   · 不用外部字体/图标库 —— 内联 SVG，符合规格「不加载外部可疑脚本」
   · 移动端优先保证：卡片单列、表格横向滚动、按钮撑满
