Pebbled leather material with creases

Build a leather node material from one Voronoi pattern read twice: distance to the cell edge for sunken creases and distance to the centre for domed pebbles, with darker rougher creases, tone noise and a light sheen. Use it for bags, shoes, seats, belts and book covers.

Limits to consider

An even pebble grain only; no stitching, wrinkles from use, scratches or pore detail. Object coordinates tie the grain size to the object's scale, so scaled objects need a matching grain scale. The bump is subtle at a distance. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
