   纯原生 CSS：无预处理器、无外部字体、无 CDN 依赖

   设计方向 ·「蓝图 / 光栅」Precision Instrument
   ─────────────────────────────────────────────────────────────
   · 深空墨色作为「仪表舱」：页头、Hero、内页横幅、页脚统一沉浸在深色画布上，
     配细密蓝图网格与极轻噪点，形成技术仪器感的第一印象；
   · 浅色区作为「阅读台」：正文区干净、留白充足，保证政企客户长文阅读舒适；
   · 毛玻璃只出现在需要「浮在内容之上」或「压住深色画布」的地方——
     导航、Hero 规格条、卡片、折叠面板。它承担分层职责，不是装饰贴纸；
   · 细节语言：1px 渐变发丝线、四角准星刻度、等宽数字与宽字距标签。

   目录：令牌 → 重置 → 布局 → 页头 → 按钮 → Hero → 内页头 → 卡片
        → 步骤 → 伙伴墙 → FAQ → 侧栏 → 页脚 → 动效 → 响应式 → 降级
