   科技感视觉升级 v2（2026-09-20）
   --------------------------------------------------------------------------
   深色舞台（首页 Hero / 内页页头 / CTA 条）改为多层光效：
     ① 极光光晕（缓慢浮动）   ② 精密网格（细格 + 粗格，向对角漂移）
     ③ 粒子星网（Canvas，site.js 注入）  ④ 扫描光带  ⑤ 细噪点（消除渐变色带）
   亮色正文区加极淡技术底纹（固定层，不影响任何文字可读性）。
   优雅降级：JS 关闭时 ①③④⑤ 不出现，底色、网格与全部内容照常显示。
   性能：动画只用 transform / opacity（GPU 合成），离屏与切后台自动暂停。
