This PR improves the dataset card by:
- Adding the `depth-estimation` task category to the YAML metadata for better discoverability.
- Organizing the links to the paper, project page, and GitHub repository.
- Updating the teaser images to use absolute URLs from the official repository.
- Maintaining the citation information for researchers.
The dataset is now correctly linked to its corresponding paper: https://huggingface.co/papers/2603.26658.
