deepseek-ai/DreamCraft3D ? reverse-engineered prompt

Build me a working version of this DreamCraft3D project that can take a single input image and turn it into a high quality 3D object.

I want the full flow to work, starting with image preprocessing to remove the background and get depth and normal maps, then run the staged 3D generation process, and finally let me preview the result in a simple app or demo page. If it needs pretrained models or extra setup, wire that in clearly and make it easy to run with one or two commands. A small interface where I can upload an image, enter a text prompt, and start the generation would be great.

Please make sure the code runs cleanly, includes sensible defaults, and give me clear instructions for installing everything and launching the demo. If you need to check the latest docs or model links online, go ahead and do that.
