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)

Current Resource Hints
9 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/9a800f173b8d9e8f-s.p.3nglv5iys3s0a.woff2. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.

This script has high main-thread execution time — optimize hot paths or defer.
Source: web.dev
52% of Google Tag Manager's code is unused. The script may be loading features you don't use.
Bundle has high unused-code ratio — tree-shaking and route-splitting recover the wasted bytes.
