Nice work! I noticed the credit to Wikimedia Codex at the end of the post. As a supporter of both the OpenStreetMap and Wikimedia, it’s great to see this kind of cross-pollination of ideas and resources. It would have been fantastic to acknowledge this a little more prominently. I would have loved to hear at least a brief mention of how it inspired you and what elements of it you intend to remix or reuse. That would be a great way to show appreciation and foster goodwill and potential collaboration.
