/* Local site of ai-daily-brief. Reader layout: one sans family, cards separated by space.
   Colors: --official is the single hue (官方, 新, links, switches); --accent marks 重要 only.
   Light scheme follows pi.dev (warm stone paper, slate ink, square corners); dark follows Tripo Research
   (pure black, gray cards without borders, white at several opacities, pill controls).
   html[data-theme] is auto|light|dark; the head script resolves it into html[data-scheme]. Density on html[data-density]. */
