Protomaps is astonishingly cool technology.
You can serve a full map of the world from static hosting, retrieved by clients using fast HTTP range requests.
You can also create your own subset map. I created my own self-hosted vector map of Half Moon Bay, California and it’s less than 2MB (and thanks to range requests even smaller to serve to a browser) despite having building-level outlines: https://til.simonwillison.net/gis/pmtiles
