summary
Webpages prioritize readable text by shipping a simple strategy: declare system fonts by default, load custom fonts asynchronously, watch their promises, then flip a class on the document to swap families. Implementation uses a small loader (for example FontFaceObserver), CSS class rules and optional network hints. Also use preload preconnect and font-display and consider Filament Group subset tools to cut sizes. The claim is that this prevents invisible text, is trivial to add and reliably works.
