This PR significantly improves the dataset card for HouseLayout3D by:
- Adding the `task_categories: ['image-to-3d']` to the metadata, enhancing discoverability for relevant tasks.
- Including explicit links to the official paper (https://huggingface.co/papers/2512.02450), the main GitHub repository (https://github.com/HouseLayout3D/houselayout3d), and the project page (https://houselayout3d.github.io) at the top of the card.
- Reformatting and expanding the existing "Getting Started" section into a comprehensive "Sample Usage" guide. This new section incorporates detailed installation steps (including `git-lfs`), instructions for downloading the dataset, and steps to run the visualization, all derived from the project's GitHub README for accuracy.
