/* ============================================================
   One Tap Roblox — 全站样式 v2（2026-09-30 重设计）
   视觉语言：方块城市 Sky-Blocks
   - 底色：游戏同款饱和天空蓝 + 方块云（低透明度平铺）
   - 所有内容 = 浮在天空上的「游戏菜单面板」：白底 + 3px 深蓝厚
     描边 + 无模糊硬投影 + 大圆角（Roblox 控件质感）
   - 记分牌 HUD：黄（金币/高亮）· 绿（金钱）· 红（击杀横幅）
   - 像素贴纸字（Press Start 2P）做标签；准星做章节符号
