Great step-by-step breakdown! One complementary tip: when defining your core interfaces in the Domain layer, also consider creating small, focused abstractions (like `IRepository<T>` and `ISpecificDomainService`) instead of large, all-in-one contracts. This keeps your application layers even more loosely coupled and testable.
