Very cool to see. I've been vibecoding a side project as well for learning/using the cloud-native geospatial stack (https://sylveapp.com/, quite rough around the edges) that focuses solely on processing and hosting tiles. I'm still working on getting a usable demo for my example map but seeing this helps to refine what I'm working; to focus on hosting/publishing vs visualizing/analysis.
It's fun to see all other projects that also use a similar stack (MapLibre + DuckDB + PMTiles).
