That's fair! While understandably it isn't probably a top priority, I'd highly encourage checking out https://docs.protomaps.com/pmtiles/maplibre . It can be nearly free to directly hit a single planet pmtile file, especially with cdn in front, and slightly more to put up a server in front of it (imo, not needed).

Anyway, awesome site regardless, and OSM tiles are fine if not abusing their hosting (this isn't I'm sure).
