+@ArgumentsSource(ScenarioArgumentsProvider.class) delegates argument production to a real,
+separately-compiled class implementing ArgumentsProvider -- the escape hatch to reach for once a
+data source needs more structure than @MethodSource's single static method comfortably holds
+(loading fixtures, branching on environment, composing other providers). ScenarioArgumentsProvider
+overrides the current provideArguments(ParameterDeclarations, ExtensionContext) overload rather
+than the older single-argument form, which still compiles but is now deprecated.
