Font Optimization
Self-host any font as WOFF2 with correct preload headers.
The giojs-font layer downloads and self-hosts fonts as WOFF2, then injects the correct preload and stylesheet links into your HTML — no third-party font CDN.
Self-hosted fonts are served from /_gio/fonts and cached aggressively, eliminating a render-blocking round-trip to an external host.
