/* ==========================================================================
   V2 视觉升级 · 对齐「全景视界」配色
   --------------------------------------------------------------------------
   原方案是暖白 + 墨黑 + 赤陶铜，整体偏暗。
   这里改为全景视界的设计语言：浅灰底 #F5F5F7 / 近黑字 #1D1D1F /
   蓝色主色 #0071E3，首屏由深褐渐变改为浅色，页脚同步提亮。
   追加在文件末尾，靠层叠覆盖，不改动上方原始规则。
