   NOSHASHI homepage: the intelligence layer
   ─────────────────────────────────────────────────────────────────────
   The Intelligence Core in the hero, the system strip, and the four
   narrative sections (Platform, The network is alive, Intelligence with
   evidence, Institutions). Everything is 2D: CSS, one image, inline SVG
   and a Canvas 2D graph drawn by site/assets/intelligence.js.

   It uses the page's own tokens (--ground, --surface, --ink, --muted,
   --faint, --rule, --brand, --tele, --go, --hold, --nogo, --r), so the
   light/dark toggle and the brand board apply without a second palette.
   One radius (--r, 3px) everywhere, matching the rest of the site.
   Every animation stops under prefers-reduced-motion.
