+    <!-- WireMock: standalone HTTP server with fault injection, not managed by
+         spring-boot-dependencies; pin it explicitly. The bare "wiremock" artifact no longer
+         bundles a server in the 3.x line (FatalStartupException: "Jetty 11 is not present and
+         no suitable HttpServerFactory extension was found"), and adding wiremock-jetty12 on top
+         of it is worse, not better: wiremock's own transitive deps still drag in real Jetty 11
+         modules (jetty-servlet, jetty-servlets, jetty-webapp, http2-server at 11.0.26) alongside
+         wiremock-jetty12's Jetty 12 ones, Maven's dependency mediation then picks one jetty-io
+         version for everyone, and the mismatched pair throws NoClassDefFoundError at server
+         startup for a class as basic as org.eclipse.jetty.io.WriteFlusher$Listener. The fix is
+         wiremock-standalone: a single shaded jar with its own relocated copy of Jetty
+         (wiremock.org.eclipse.jetty.*), so nothing on your own classpath can clash with it;
+         see the post. -->
