/* ==========================================================================
   FaceNest 官网样式
   --------------------------------------------------------------------------
   设计取向（详见 README「为什么是浅色」）：
     * 浅色为主 → 深色的 App 截图在浅底上自然"跳"出来，像产品照；
       同时隐私政策 / 条款 / FAQ 这类长文在浅底上更好读、更像正经文档。
     * 深色只做"节奏带"（隐私区块 + 末尾 CTA），呼应 App 的深色界面。
     * 主色 #8B5CF6 是从 App 界面上直接采样的品牌紫（按钮 rgb(139,92,246)）。
     * 字体只用系统字体栈 —— 零下载、零商用授权风险（见 README）。
