+ * Shipping lines — carriers registered by backoffice staff who sign in to the
+ * portal directly.
+ *
+ * Separate from `freight.companies` on purpose: a shipping line has no TIN,
+ * business licence, eTrade record, operational profile or onboarding state, so
+ * it shares none of the customer columns. `user_id` sits on the company row
+ * itself because the company IS the account — there is no contact-person row.
+ *
+ * No FK on `user_id`: `iam.users` belongs to the IAM service's schema, which
+ * this API reads but never owns.
