+/**
+ * A custom Maven Enforcer rule that ensures all dependencies declared with
+ * {@code type=pom} (i.e. BOMs) also specify {@code scope=import}.
+ *
+ * <p>This rule inspects both the top-level {@code <dependencies>} section and
+ * the {@code <dependencyManagement>} section of the project. Any dependency
+ * with {@code type=pom} that does not have {@code scope=import} will cause
+ * a build failure.
+ *
+ * <p>BOMs (Bill of Materials) are intended to be imported via
+ * {@code <scope>import</scope>} inside {@code <dependencyManagement>}.
+ * Using them without import scope is almost always a mistake and can lead
+ * to unexpected transitive dependency resolution.
