Things have changed. In other news, a Vite bug caused me to pin to a very specific version and now I have to fix more things. Oh well, the Svelte people wrote a really nice migration guide, and are generally very nice and helpful, so I will not complain any more than I already have.
Remaining:
[x] Fix all the warnings about unused styles
[ ] ~Fix the "used window.fetch instead of load fetch"~ Just leave it for now, whatever
[ ] ~Try to fix the "es module in worker" problem~ Vite won't help with this; however, Firefox team is currently fixing!!!
