Seamless Texture Brown Leather Surface Feature

Create a seamless texture of a dark brown leather background. The surface should feature a subtle grain pattern, resembling natural leather, with varying shades of brown to add depth. Instead of any branding or text, include small, random imperfections like scratches or marks to give it a realistic and organic feel. The overall look should be rich, inviting, and suitable for applications in upholstery or fashion design. Make sure the edges blend smoothly for a continuous pattern.
