Try with html stream

[paoloricciuti]

Describe the problem

In theory the best way to handle this would be with actual html streaming. I've read it doesn't work with sveltekit and i didn't even tryed but make a small POC might be worth the shot.

If it doesn't work we could always do the same when sveltekit will support html streaming.

Describe the proposed solution

Stream goes brrr
