I built Stamp, a Gmail-style inbox, to explore the new 𝚗𝚊𝚟𝚒𝚐𝚊𝚝𝚒𝚘𝚗() API in Next.js 16.4. Sometimes you want to cache content for return visits without prefetching it before someone opens the page. In this mailbox, visible links prefetch each thread's header. The message bodies still use '𝚞𝚜𝚎 𝚌𝚊𝚌𝚑𝚎', but 𝚊𝚠𝚊𝚒𝚝 𝚗𝚊𝚟𝚒𝚐𝚊𝚝𝚒𝚘𝚗() keeps them out of the prefetch. They load after the click but will still be reused when you return. Live demo, source code, and docs below ↓
