Changes: sand diffuse, OpenGL normal and displacement preserved at 2K, converted to WebP; material tint/UV changes. Other materials at 1K.
HDRI retained as a 2K HDR texture.

Anchor GLB: original forged Admiralty anchor mesh created for Murat Şimşek.
Rebuild script: tools/ocean-models/build-anchor.cjs (Node.js).
This is an authored model; it is not a scan of a real anchor.

This work is based on “Blue crab” by Julian Johnson-Mortimer.
Changes: UV-aware meshoptimizer reduction to 83,048 triangles, fine hairs
removed at website scale, photographic 2K body/limb textures retained,
21-bone periodic walking rig added. Two independent skeletons share textures
and geometry. This is an authored textured model, not a photogrammetry scan.
No endorsement by the original creators is implied.
