/* =========================================================================
   Mitrue Tech — 科技公司主题主样式
   设计语言（依据《2.VI 与视觉风格规范》）：
   - 色彩体系：深空蓝 #0A1628 + 品牌亮蓝 #0066FF + 大量中性灰 #F5F7FA/#E2E8F0
   - 品牌蓝仅用于强调与 CTA，严禁大面积铺设亮蓝色块作为网页背景
   - 图形语言：Logo 右上角像素网格 → 深色背景辅助底纹；
               Logo 锐利折角 → 卡片切角 / 步骤连线；避免大面积高饱和渐变与卡通插画
   - 科技感：数据图表、架构图、高清产品截图、等宽字体（数字/代码），而非滥用发光特效
