Who has the fastest website in F1?

In terms of user experience, we’ve got 6.8s of nothing, then a spinner until 13.7s. Showing a spinner is definitely better than showing nothing, but only just. Chrome Devtools’ code coverage tool says over 80% of the CSS is unused for first render, along with 75% of the JS.
