    Variable mapColorsLightDarkConst

    mapColorsLightDark: (
        { land, label }: Pick<Required<MapColors>, "land" | "label">,
    ) => LightDark

    Whether map colours make a light or a dark map (dark when labels are lighter than land), to apply them over a style of the same. StylingFoundationsModule.setMapColors keeps the loaded style's shade offsets, which a dark land over streetLight clamps to black. It tells what auto chose.
