   CORELIA LANDING - Shared public-landing stylesheet.
   Used by: corelia.app (Corelia suite overview) + each app's own public
   landing (build, airfact, plan, connect). Self-contained - defines its own
   tokens so it works without any other CSS loaded.

   Design language intentionally mirrors the app-dashboard tokens
   (components/tokens.css) + buttons/cards patterns so the marketing site
   feels continuous with the signed-in product.

   Change the tokens / primitives here and ALL landings update.
