   暴风影音主题站 · 站点主题层 theme.css（必须在 global.css 之后加载）
   ------------------------------------------------------------------------
   主题色取自站点根目录 logo.png（实测：#0868B8 7.0% / #0858A8 5.3% /
   #D8E8F8 5.3% / #084898 4.8% / #0878B8 3.4%，即暴风标识的深天蓝）：
   主色走 logo 深蓝，渐变一端提亮到青蓝（logo 高光 #D8E8F8 同族），另一端压深，
   形成「青蓝 → 深天蓝 → 藏蓝」同色系渐变。
