Lighting effect on terrain?

[larsmaxfield]

Has anyone implemented lighting of terrain directly in maplibre-gl-js, or perhaps see a path towards doing so?

Something similar to how the surface reflects light in deck.gl TerrainLayer:

I'd like to enhance our users' perception of 3D surfaces beyond hillshading and the parallax caused by 3D movement, but I'd like to stay within the mechanisms of this library.
