Original prompt

This section details on the original issue you should resolve

<issue_title>Optimize web performance and Core Web Vitals</issue_title>
<issue_description>## Summary

  • Web performance directly impacts user experience, SEO rankings, and conversion rates.
  • Optimizing Core Web Vitals (LCP, FID, CLS) should be a continuous focus.

Acceptance Criteria

  • Run performance audits (Lighthouse, WebPageTest) and establish baseline metrics.
  • Optimize for Core Web Vitals:
    • Largest Contentful Paint (LCP) < 2.5s
    • First Input Delay (FID) < 100ms
    • Cumulative Layout Shift (CLS) < 0.1
  • Implement performance optimizations:
    • Code splitting and lazy loading for routes/components
    • Image optimization (next/image, WebP/AVIF formats)
    • Font optimization (preload, font-display: swap)
    • Remove unused CSS/JS (tree shaking)
    • Minify and compress assets
  • Set up performance monitoring in production (Real User Monitoring).
  • Add performance budgets to CI (fail builds if bundle size exceeds thresholds).
  • Optimize third-party scripts (defer/async, minimize impact).
  • Consider edge caching and CDN for static assets.

The edge runtime is configured, but there's no comment explaining why edge runtime was chosen over Node.js runtime. Adding a comment would help future maintainers understand the performance/architectural decision (e.g., lower latency, global distribution).

navigator.sendBeacon() may return false if the beacon cannot be queued, but the return value is not checked. This could result in lost metrics without any error handling. Consider checking the return value and falling back to fetch if it returns false.

The supportsWebP() function creates a new Promise and Image every time it's called. Consider memoizing the result since WebP support doesn't change during a session. This would prevent redundant checks and improve performance.

The formatBytes function has a potential issue when bytes is negative. Math.log() of a negative number returns NaN, which will cause incorrect output. Add validation to handle negative values or document that negative values are not supported.
