   喵数据 · 首页 v5「Design Polish Layer」
   ------------------------------------------------------------
   覆盖层：在 style.css + home-v4.css 之后加载，仅升级视觉，
   不删除、不改变任何功能与交互逻辑（可整体移除回滚）。
   v5 设计决策（2026-10-16，按已确认风格规范）：
     · 基底不变：深空黑 #05070F / 品牌蓝 #007AFB / 冰蓝 #52DBFD
     · 新增强调色：青绿 #2FE0C0（增长/新数据/在线态）
                  琥珀 #f5b544（VIP / 特殊高亮）
     · 圆角令牌：卡片 12px · 按钮 8px · 标签 999px
     · 层次：发丝边 + 微阴影 + hover 上浮；区块留白加大
     · 动效：克制，仅 hover/入场过渡，尊重 prefers-reduced-motion
