This PR significantly improves the model card for **ShadowDraw: From Any Object to Shadow–Drawing Compositional Art** by:
* Adding the `pipeline_tag: text-to-image` to enhance discoverability on the Hugging Face Hub for generative image tasks.
* Including a direct link to the paper: [ShadowDraw: From Any Object to Shadow-Drawing Compositional Art](https://huggingface.co/papers/2512.05110).
* Adding links to the official project page: https://red-fairy.github.io/ShadowDraw/.
* Providing a link to the GitHub repository: https://github.com/Red-Fairy/ShadowDraw.
* Incorporating detailed "Installation" and "Generate Your Own Shadow-Drawing Art" sections directly from the GitHub README, including code snippets for easy replication.
* Retaining the existing `license: cc-by-2.0`.
This update makes the model card comprehensive and immediately useful for users interested in the ShadowDraw framework.
