## Ejemplo

```python
# Comentario top-level
metabase_create_document_comment(client, 29, {
    "type": "doc",
    "content": [{"type": "paragraph", "content": [
        {"type": "text", "text": "Deberiamos anadir un paso para configurar Slack"}
    ]}]
})

# Respuesta en thread
metabase_create_document_comment(client, 29, content=reply_tree,
                                  parent_comment_id=1)

# Anclado a un bloque concreto del documento
metabase_create_document_comment(client, 29, content=tree,
                                  child_target_id="48f9a7a4-79a0-a282-03a1-ffe2f76b9106")
```

## Notas

`target_type` se fija internamente a `"document"` (unico valor aceptado por la API en v0.59).

El `content` sigue el mismo schema ProseMirror que los documents (ver whitelist en `metabase_validate_document_payload`).
