+//! DHL shipment creation. See `docs/integrations/dhl.md`.
+//!
+//! DHL has several APIs (Parcel DE Shipping, eCommerce, MyDHL Express) behind
+//! one developer portal; which one applies depends on your contract and the
+//! markets you ship to. As with DPD, the workflow is fully wired — only the
+//! authenticated HTTP call is left as a marked TODO so we don't ship an
+//! unverified payload.
