The internet is slow, but Google says your website should be fast. Google can't meet their own standards but that doesn't matter. All that matters is there's now a cost added to creating a website because Google will punish _your_ content for loading slowly while _their_ content (and the content of their buddies) can load slowly. The Spinner helps tell users that a page is loading and it's typically used with `{#await}` and the `client/helpers.js:defer()` function. Find or create examples in the project for how to do this. Adding an `aspect_ratio` also helps you with page load speed because the page renders, it has less layout shift, and there's a notification that it's done. Best of all the spinning is done in CSS which doesn't count toward "execution" in Lighthouse.
