+          Exclude problematic versions from the parent:
+
+          The parent POM includes newer versions of SLF4J (2.x) and Logback (1.5.x)
+          that are not compatible with the Spring Boot 2.7.x logging setup, which
+          relies on SLF4J 1.7.x and Logback 1.2.x. If these newer versions remain,
+          they cause runtime errors due to classes like org/slf4j/impl/StaticLoggerBinder
+          no longer existing where Spring Boot expects them.
+
+          By excluding these dependencies, we ensure that our module only uses versions
+          of SLF4J and Logback that align with the Spring Boot ecosystem. This approach
+          helps prevent `NoClassDefFoundError` issues and ensures stable, expected
+          logging behavior within this module.
