The bundled tables are 256 samples quantized to RGB8. They are color data only;
all normalization, cartography, layout and rendering are implemented by Azimlib.
The five-stop viridis scale in styles.py and its development baseline is also
CC0 color data; it is not claimed as original Azimlib artwork or a new palette.
