Create an ultrarealistic design of vintage western carpet with beige and brown color, featuring a traditional Native American pattern in the center on white background. The patterns should include triangles pointing up or down against dark lines to create contrast between colors. Add some texture for depth using roughness or graininess. Ensure that each shape is clearly defined while maintaining elegance. Use soft lighting to highlight details. –s 400–v5.2 –style raw –q32 --ar 1:2  --s 250
