framed wall picture 3d model

Create a realistic 3D model of a framed wall picture. This is a wall frame object, not a sculpture. The black outer frame should be 3D with proper thickness and depth (about 3-4 cm). Include a white mat border inside the frame with slight thickness. The artwork inside must remain completely flat as a 2D printed texture. Do NOT generate any depth, relief, embossing, or 3D geometry for the fish or the painting content. The painting must be a flat rectangular plane with texture only. Model structure: - Outer black frame: 3D solid geometry - Inner white mat: thin 3D layer - Artwork: perfectly flat plane with texture Realistic proportions, clean geometry, no sculpted details on the artwork surface.
