/* skarn-web shared stylesheet (GEO net-new pages).
   Extracted from the brand tokens in the existing index.html so /compare/, /about/, and /research/
   share one self-hosted stylesheet. Using an external /style.css (style-src 'self') keeps the strict
   CSP simple across multiple pages - no per-page inline-<style> hash to maintain.

   NOTE for the site-opt session: populate the @font-face block below with the self-hosted woff2 paths
   you create under /fonts/. Until then the pages fall back to system fonts gracefully. */
