💻 Developer Notes

If you are curious about how the tiles are requested, the logic follows a basic coordinate system:

// Conceptual tile request logic
void fetchTile(int x, int y, int z) {
    string url = "https://tile.openstreetmap.org/" + z + "/" + x + "/" + y + ".png";
    downloadAndRender(url);
}
