        Supports both legacy offset-based and cursor-based pagination.
        Cursor fields (``has_more``, ``after``, ``before``) are populated for
        cursor-paginated endpoints.  Legacy fields (``offset``, ``limit``) are
        populated when the caller uses the deprecated ``offset`` parameter.
