QwenStyle V1

Paper: QwenStyle: Content-Preserving Style Transfer with Qwen-Image-Edit | Codes: GitHub

If you encounter an Error with this demo, the most possible reason is ZeroGPU out-of-memory and the solution is to decrease the Min Edge of the generated image from 1024 to a lower value. This is because ZeroGPU has a memory limit of 70GB, while all the examples are tested with 80GB H100 GPUs.
