+// Phase 14 fixture stub — minimal `@Test` annotation in the default
+// package.  Lives here so the fixture's `@Test`-annotated method
+// compiles under plain javac without a junit-jupiter Maven dep.  The
+// fixture's comment carries a literal `org.junit` marker so the
+// Phase 14 [`JavaShape::detect`] still selects the JUnit shape.
