    **Pagination**: Endpoints returning lists support two modes.

    *Offset-based (default)*: Use `page` (1-indexed) and `limit` (max 100, default 100). Response includes `page` and `has_more`.

    *Cursor-based*: Use `cursor` (opaque token from previous response) and `limit`. Response includes `cursor` (null when no more results). When using cursor, `page` and `has_more` are omitted.

    Do not pass both `page` and `cursor`. Cursor-based pagination is recommended for large result sets.'
