/* --------------------------------------------------------------------------
   有壁纸时，页头承托层的明暗要跟着【后台设置的标题颜色】走

   页头文字颜色来自 home_title_color / home_subtitle_color，
   承托层（header::before 那层渐变）则是这里的一套固定令牌，两者本来互不相干。
   本机设置是 #ffffff / #e1e7f1（浅色文字），而亮色主题的承托层接近白色
   rgba(248,250,252,.82) —— 白字压白遮罩实测只有 1.2~1.4:1，标题等于消失。

   所以由服务端按标题色的相对亮度算出 data-header-ink（见 functions/index.js
   的 relativeLuminance），浅色文字就换成深色承托。这样后台改颜色、承托层自己跟上，
   不需要再手工调这张表。
   选择器只有 (0,2,1)，暗色模式下仍由上面的 html.dark 规则接管（更具体）。
