Catalog Format

The remote catalog is a JSON file with this shape:

{
    "name": "dark HUB Prompt Catalog",
    "version": "1.1.0",
    "updated_at": "2026-03-26T12:00:00Z",
    "prompts": [
        {
            "id": "fashion-editorial",
            "title": "Fashion Editorial",
            "prompt": "editorial fashion portrait, tailored styling, clean composition",
            "image": "previews/fashion-editorial.svg",
            "tags": ["fashion", "editorial"]
        }
    ]
}

Relative image paths are resolved from the catalog location, which makes GitHub raw catalogs easy to manage.
