LayerInfo

A single layer definition with metadata.

Combines the GDS layer identity (number, datatype) with display properties (color, fill, opacity) and a human-readable description.

Use info.layer to get the underlying Layer for rosette APIs:

layers = load_layer_map()
cell.add_polygon(poly, layers.silicon.layer)
