  "prompt": "Generate a photoreal flat square 1024+ PBR diffuse/albedo close-up of hand-laid cross-cut colored pencil offcuts in a decorative wood inlay. A nonperiodic terrazzo-like arrangement of densely packed small offcuts in several modest sizes, at random orientations. Many hexagonal pieces have small circular teal, red, green and ochre pencil cores with realistic wood-grain surrounds. Small odd irregular slivers of pale wood fill gaps. No coherent rows or perfect repeating lattice. Uniform average brightness and density across the entire surface, precisely neutral flat diffuse orthographic illumination, no glaze highlights, perspective, signage, pencil bodies, seams or borders. Full bleed and designed to repeat at edges without a hard line.",
