## Notes

- **Time zone**: Mexico spans several zones and the page prints none, so only `localTime` is set and `timestamp` is `null`.
- **Wording**: scans are in Spanish, as `Stage: remark` (for example `Entregado: ENTREGADO AL CLIENTE`).
- **Source**: the server-rendered `castores.com.mx/rastrear.html` page; no login.
