/* public/css/site.css
   Shared design system for the PUBLIC pages (service pages, services hub,
   About, Founder, 404). Same brand tokens as the app (blue/sky, Space
   Grotesk + Inter) so the public site and the app read as one product.
   The in-app screens keep their own inline styles on purpose. */
