Now that the origin serves directly (no CDN compressing for us): - Add gzip + brotli response compression — homepage HTML 84KB -> ~25KB (~71% smaller), big Core Web Vitals / crawl-budget win - Baseline security headers on every response: X-Content-Type-Options, X-Frame-Options, Referrer-Policy (no HSTS yet — cert just stabilised) - Long-cache immutable GUID uploads (Cache-Control max-age=30d,immutable) Verified locally: gzip+br negotiated, headers present, uploads cached.
