/* ============================================================
   安超充门户 V6 — 深空电光（Deep Space Electric）
   ─────────────────────────────────────────────
   参考 uisdc 粒子动效趋势，核心手法：
   · 打散重组（Deutser）—— 粒子在星云/能量环/闪电三态间 morph
   · 向中心收拢（Petar Stojakovic）—— 能量环态营造深邃
   · 粒子环聚焦视线（Seven Brief Lessons）—— 环态把注意力收到文案
   · 鼠标联动（Double Pi / Sony）—— 力场排斥 + 弹性回归
   配色：深空底 + 电光青/蓝紫，品牌红作为唯一暖色锚点（Logo/CTA）
   对比度：正文 ≥4.5:1，非文本/大字 ≥3:1
