   云起技术官网 · 字节风设计系统 (yunqi.css)
   ------------------------------------------------------------------------
   设计方法论（借鉴字节跳动官网，不复刻其品牌资产）：
     · 固定高饱和「云起蓝」顶部导航 + 同色页脚
     · 使命型首屏：真实业务大图 + 白色使命面板（短标签 + 一句强主张）
     · 左右交错内容区，标题短、描述克制，图像约占半屏
     · 克制小圆角（卡片 8px / 按钮 6px / 标签 4px），仅使命面板用大圆角作记忆点
     · 大留白：桌面内容左右安全边距 ≈ 8vw，区块间距 > 区块内部间距
     · 品牌点缀：统一为 #3083fa，用于 hero 标签 / 关键数字 / 主 CTA
   该文件即「设计系统样板」，后续内页统一复用本套 token 与组件。
