Use Vite (again) to reduce website size

Here's some data:

Netlify: Transferred 78kB JS + 5.17kB CSS / Size 255kB JS + 26kB CSS
Prev. commit: Transf. 922kB JS + 122kB CSS / Size 922kB JS + 122kB CSS
This commit: Transf. 257kB JS + 26kB CSS / Size 257kB JS + 26kB CSS

I am pretty sure I could reduce Transf. through Accept-Encoding stuff
