Describe the Bug

Starlight, as well as the Astro docs, have a large sticky navigation header that consumes a lot of vertical space. Occasionally, I prefer to zoom in when reading any documentation, and as a consequence I have a lot less room to read than I would otherwise if the navigation header wasn't fixed.

I'm interested in Starlight, though I would like to see this navigation treatment improved; either to keep it at the top of the page, or auto-hide as I scroll down. Check out how navigation is handled on the new Svelte website on desktop and mobile: https://svelte.dev/
