 * IMPORTANT NOTE REGARDING GOOGLE FONTS IN PRODUCTION:
 * For a fully production-ready website, it is highly recommended to download the font

 * E.g., @font-face { font-family: 'Inter'; src: url('fonts/Inter.woff2'); }
 * 
 * Why? 
 * 1. Faster render speed (bypasses third-party DNS lookup).
 * 2. Caching efficiency.
 * 3. Prevents GDPR liability (Google tracks IP addresses when serving CDN requests).
