🤩 Loving these maps! I missed your comment about using the stamen tiles for static maps.
I use https://github.com/dfacts/staticmaplite on my site. It’s no longer under development but, as long as you point it at a working tilemap server, it works fine! I switched out the URLs hardcoded in the PHP file for the Stamen “Toner” tiles, using the tile server URL pattern on the Open Street Map wiki.
