3. Technical Deep‑Dive

3.1 Front‑End

| Feature | Pre‑Patch | Post‑Patch | Rationale | |---------|-----------|------------|-----------| | HTML5 Boilerplate | Basic, missing lang attribute. | Added lang="en" and ARIA landmarks. | Improves accessibility and SEO. | | CSS Framework | Bootstrap 4 (custom overrides). | Upgraded to Bootstrap 5, removed jQuery‑dependent components. | Smaller bundle, no jQuery dependency for UI, reduces attack surface. | | JavaScript | Inline scripts, unescaped user input. | All scripts moved to external files, strict CSP (script-src ‘self’ ‘nonce‑…’). | Stops reflected XSS. | | Service Worker | Cached all requests (including ads). | Switched to “Network‑First” for /ads/ endpoints; added versioned cache name. | Guarantees fresh ad content, avoids serving stale or malicious ads. | | Responsive Images | JPG/PNG only. | WebP + srcset, lazy‑load via IntersectionObserver. | Faster load on mobile, lower bandwidth. | www 420wap com patched
