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)

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/36363bfb06833f56-s.p.d8302362.woff2, /_next/static/media/6d5d99631d01f2a2-s.p.e3e80618.woff2, /_next/static/media/7546fe8f902b88b8-s.p.5f7c9333.woff2 (+3 more). Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
Performance issues directly impact user engagement and conversion rates.
