List every ProfileKit card type (stats, hero, snake, ...) with a one-line description and the required params for each. Use this before calling render when the user asks what cards exist or which to use. Catalog is fetched live from ProfileKit on first call and cached per process.

List built-in ProfileKit themes (dark, tokyo_night, kanagawa, rose_pine, ...). Any card accepts ?theme=<name>. For fully custom palettes use ?theme_url= pointing to a JSON gist.

Build a ProfileKit card URL plus ready-to-paste markdown and HTML snippets for the given card type and params. Does NOT fetch the SVG itself — the URL is what consumers embed. Call list_cards first if unsure which type or what params the user's card accepts.
