   Privateer site.css - the shared design system for the static marketing pages
   (overview, cli, desktop, extension, harbor, pricing, api-pricing, models,
   fund, support, security, privacy, terms). Linked as /site.css; unhashed, so
   render.yaml serves it no-cache.

   A page owns only what is unique to it (in its own <style>); everything a
   second page could want lives here. Page styles must read these tokens rather
   than restating colours, so one edit here re-skins the whole site.
