Prefetching pages doesn't require a frontend framework though. All it takes is a simple script to preload all or specific anchor links on the page, or you could get fancier with a service worker and a site manifest if you want to preload pages that may not be linked on the current page.
Yep, that works as well. I'll reach for a script still if I want more logic around when to prefetch, like only prefetching on link hover or focus. A script is also needed for any links that you need to preload but aren't included on the current page.
