Preload Hints

HTML link hints that tell browsers to fetch important resources early.

Resource hints include preload (fetch this resource now), prefetch (fetch later for next navigation), preconnect (establish connection to origin) and dns-prefetch (resolve DNS in advance). Preload critical fonts, hero images and important JavaScript to improve LCP. Misuse can degrade performance by competing with critical resources.
