/* ==========================================================================
   themes/alt/genesis/genesis.css
   Page-scoped styles for /indexalt.php only. Prefix: gen-*.

   Palette/fonts: 100% inherited from Meridian via the legacy-bridge vars
   (--text-*, --bg-*, --glass-*, --f-display/--f-mono/--f-ui, --text-violet,
   --text-accent) already wired by shared/page-shell/lx/public.php. No new
   color tokens are introduced here — see themes/alt/genesis/motion-brief.md
   for the rationale (AI-loop nodes use --text-violet, human nodes use
   --text-accent-gold via --lx-accent, exactly as already bridged).

   Layout/rhythm/motion: cofounder.co-informed — large bold serif headline,
   generous vertical section rhythm (140px+ desktop gaps), numbered feature
   modules, dark-leaning glass cards, scroll-pinned centerpiece section.
