   UnitSense Marketing — styles.css
   Shared editorial / Riso design system. Tokens ported from the product
   (unitsense/dashboard globals.css, via docs-site/css/docs.css) so the
   marketing site matches the portal + docs. No Tailwind, no build step.
   Components use token vars only — never hardcode hex — so dark mode is free.
