Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
JavaScript bundle is large — code-split routes and lazy-load off-screen components to defer.

Optimization checklist
- Preload critical fonts (priority=high)
- Use woff2 format for all fonts
- Set font-display to swap, optional, or fallback
- Subset large fonts (≤100 KB each)

A+Critical Rendering PathNo render-blocking resourcesPASS
AResource Hints3 hints, 0 missing preconnectsPASS
Current Resource Hints
3 resource hints configured
Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: /_next/static/media/1b99372b3eaef0c8-s.p.0gx2haw2tmll8.woff2, /_next/static/media/fba5a26ea33df6a3-s.p.0eehd8tgys7nv.woff2. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
Performance issues directly impact user engagement and conversion rates.
