Also added a privacy disclaimer.

lighthouse looks good but not sure if the defer works as expected 🤔

This is desktop lighthouse though, right? You need to check mobile lighthouse as well!

Looks like over 50% of the code bundle is still unused, and it's also loading immediately and not only once we click on the button:

It's still dragging down all the scores but I guess it's more useful to us if it's there?

Agreed!

Thanks 🙏

They want to improve it but its not on the immediate roadmap, so at least 2+ months out.
I will keep on it though.

one more thought: could we just disable it on mobile, where it hurts the scores more?
