   ImpactMojo BookSummaries — Dark Mode
   BookSummaries share a consistent CSS variable system (--bg, --card, --text,
   --muted, --border, --accent, --accent-light, --teal, --teal-light) defined
   in their inline <style> with the warm cream editorial palette.
   This file overrides those variables in dark mode so the existing CSS
   (which uses var(--bg) etc) automatically adapts. No filter-invert,
   no per-page rewrites.
