+/// `InitializableDependency` signifies that it has asynchronous setup work to be done
+/// before it can be used effectively. The setup is done in the `init` method.
+///
+/// This is particularly useful for classes that depend on resources such as
+/// File I/O, Network calls, Database access, etc. which cannot be performed
+/// synchronously during object construction.
+///
+/// This abstract class contains a single method, `init()`, which is expected
+/// to contain all asynchronous initialization logic for the implementing class.
