 * {@link EmployeeAuditLogger}, a plain collaborator bean unrelated to REST at all.
 *
 * <p>The client builds itself from an injected {@code RestClient.Builder}, the same shape as
 * {@link EmployeeTemplateClient}'s {@code RestTemplateBuilder} constructor - this is what lets
 * {@code @RestClientTest} wire a mocked client straight in, with no separate {@code RestClient}
 * bean required (see {@link EmployeeHttpInterface} for the one case that does need one).</p>
