The HDRI is 1024×512 Radiance RGBE. All six PBR maps are 1024×1024 JPEG. Maps were downloaded unchanged from official Poly Haven links, and byte sizes plus MD5 checksums verified against the public API. Exact URLs, checksums and paths are in manifest.json. Total media payload: 3,808,199 bytes.

For Three.js: diffuse maps use SRGBColorSpace; normal and roughness maps use NoColorSpace. Normals are OpenGL orientation. Floor material covers 2×2 meters per repeat; marble covers 1.5×1.5 meters. The wooden boards run horizontally in the image. Darken the warm pine albedo with the material color if the scene calls for dark flooring. Marble 01 contains slab seams; use UV scaling/offset to frame a single slab on a plinth face if desired.
