The less cheery stuff is certainly hard to hear, but is what I need to hear, so I appreciate it. There is clearly something really really wrong with either the GraphQL server hosted on GCP or with how I'm fetching it from the frontend. Really need to dig into this.
What do you mean by non-navigable using keyboard?
Maybe server-side generation with cache would help initial load?
Still a problem when I don't remove uBlock.
As for keyboard, there seems to be some unclear to me focus grab which meant that I couldn't even attempt to scroll the page using arrow keys. Mind you, it's not just your site that does it, usually it's related to someone being a bit too fancy with autofocus on a searchbox. Not sure how to help there, web frontend is not exactly my forte :)
