TODO

Add server cache headers for static assets (CSS/JS/icons/SVG/webfonts) — e.g., Cache-Control: public, max-age=31536000, immutable for assets and must-revalidate for HTML.
Consider hashing asset URLs (CSS/JS) to pair with long-lived caching.
Optimize remaining small icons (32/128 PNGs) or add WebP fallbacks to favicon links.
Optional: download/add FA regular/brands webfonts to cache (or strip unused @font-face blocks) to trim unused CSS warnings.
Explore further CSS optimization (critical inline for first paint) if needed.
Validate Lighthouse after these changes to confirm FCP/LCP improvements.
