## Why it matters

Fonts are often the biggest render-blocking resource on a page. Each font family adds 50-200 KB to download. Too many fonts slow down LCP (Largest Contentful Paint) and degrade Core Web Vitals.

## In practice

A site with 1-2 Google Fonts families loads optimally. A site with 6+ different fonts and Font Awesome icons can have a first render that is 500 ms or more slower. Self-hosted WOFF2 fonts are faster than Google Fonts CDN.

## How be1st checks it
