Next.js automatically optimizes fonts (including Google Fonts) by hosting them locally and removing external network requests.

Architectural Implication
Generated once at build-time. Near-instant delivery from global CDNs with zero compute overhead per user.
Executable Code Workbench

11}Mental Model
Bringing the fonts home. Instead of the browser asking Google for a font every time, Next.js downloads it once at build time.
Why This Exists
To prevent 'Layout Shift' (where text jumps when fonts load) and to speed up page loads by eliminating external font requests.
Critical Note
"Developers often confuse this pattern with traditional client React. Use the Live Code Workbench above to simulate execution."
