Test these with pmtiles CLI and compare visually:
The images should match what you see in the viewer at those coordinates!

Quick test:
pmtiles tile raster.pmtiles 5 6 10 > cli_tile.png
curl 'https://tile.map.one/test_pm/tile.php?tile=raster.pmtiles&z=5&x=6&y=10' > php_tile.png
compare -metric AE cli_tile.png php_tile.png diff.png

If they're identical, coordinate system is correct!
If different, we may need to flip Y axis (TMS vs XYZ)
