ALL REQUESTS are prefetched on hover .

(SSR) waits for the data to be fetched before rendering

(Loading) shows a loading state (Data is not SSRed)

ALL data is queried ONLY ONCE per page regardless of SSR or Loading
and reused in hydration

Try this in your terminal:
curl https://orpc-svelte-query-ssr.vercel.app/userSSR/1
