OptionalcolorFill color: a hex string ('#FF5733'), a palette name ('blues', see colorPaletteIDs), or a MapLibre expression
for data-driven styling (e.g. ['get', 'color']).
Overrides the top-level GeometriesModuleConfig.color for the fill, and for the border
unless line.color is set. A feature's own color property
overrides it.
OptionalopacityFill opacity, 0 (transparent) to 1 (opaque). Also accepts a MapLibre expression.
Fill configuration for geometry styling — the interior color and opacity.
