   Clear Path Advertising — site.css
   Design system derived from the hero photograph:
   deep navy glass architecture, electric-blue data light, dusk-gold horizon.

   QUICK-SWAP DESIGN TOKENS
   ------------------------
   Change the values in :root below to re-skin the entire site. Every
   component reads from these variables — no hard-coded colors elsewhere.

   Original CONFIG tokens are preserved in comments beside each swap so the
   template can be reverted to the warm terracotta scheme in one pass.
