I believe best practice is to sort out which of your CSS is needed to render above-the-fold content, separate that out into a smaller file, and serve that higher in the page or even inline it. The rest of the CSS can be served at the bottom, with the JavaScript.
That is correct. It can just be a pain to do intuitively as all sites are different. Vuetify Documentation runs off of the vuetify webpack-ssr vue cli template which I recently removed that functionality.
If anyone has a better plan, I'm all ears!
