Original downloads follow `https://dl.polyhaven.org/file/ph-assets/Textures/jpg/1k/{asset}/{filename}`. File metadata was obtained from `https://api.polyhaven.com/files/{asset}`. Diffuse channels use sRGB; normal and roughness channels use linear data. Maps are tiled at room/maze-appropriate scale, with material tint and reduced normal strength.
