    - `links` object[] — Navigable HATEOAS links to related resources. Each entry has a `name` (RFC-5988 link relation like `self`, `edit`, `related`), an `href` URL, and a `type` (`Api` for callable endpoints, `App` for browser-facing URLs). Prefer following these `href` values over constructing URLs by hand.

The kind of resource this link points to (e.g. `Workflow`, `Task`, `Comment`).
      - `type` 'Api' | 'App', required — Whether this link targets an API endpoint or a Process Street app URL. `Api` — a callable API endpoint you can fetch directly. `App` — a browser-facing URL in the Process Street UI.
  - `links` object[] — Pagination links. When the result has more pages, look for an entry with `name: "next"` — its `href` is the URL to fetch the next page. Absence of `next` means there are no more pages. For single-resource responses this array is typically empty.
