/**
 * ISO-3166-1 alpha-2 ↔ alpha-3 mapping.
 *
 * commercetools uses alpha-2 uppercase (`"DE"`); Acuris's API uses alpha-3
 * lowercase (`"deu"`). The translation happens at the connector boundary so
 * the storefront stays in commercetools-native vocabulary throughout.
 *
 * The map covers every ISO-3166-1 country code (~250 entries). Unknown
 * inputs are passed through unchanged so the helpers degrade gracefully
 * rather than throwing in a checkout hot-path.
