## Notes

- **Guide or tracking code**: both the 22-character guide and the 10-digit tracking code work. Only the guide shape auto-detects; a bare 10-digit code needs `?carrier=estafeta`.
- **Label only**: a guide that exists but has not been handed to Estafeta returns status `label_created` with one undated event.
- **Local time only**: Mexico spans several zones and the page prints none, so `timestamp` is `null`. Descriptions are in Spanish.
