A SteamVR dashboard patch (vr-pet) drawing a baked 3D pet next to the windows: the Toon Cat in five coats, a Shiba Inu, a Fox and a Dachshund, plus models from steamFrame.pet.extraModels. It walks around, follows, sits, lies and sleeps, can be picked up by its grip bar, petted and switched in its menu; its spot, pose and model are saved state. Also the vr-pet command, "Pet" in the "+" menu with the current model's icon (steam-frame-nix-pet-icon), the flake outputs pet-models, pet-icons and pet-preview, and the check pet. A built-in model with "private": true fails evaluation; private models belong in extraModels.
