Polished marble material with turbulent veins

Build a node material for polished marble: thin veins from a noise-bent sine, soft clouding, a faint vein bump, slight subsurface and a clear coat, with vein count, width, direction and colours as parameters. Use it for floors, counters, statues and luxury interiors.

Limits to consider

The veins are a single family of turbulent sine bands, so they run broadly parallel; branching and crossing veins of real marble are not reproduced. Object coordinates tie the pattern to the object's scale. The subsurface weight is small and stylized, not measured. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
