+Designing clear and consistent error responses in a REST API is often harder than it looks. Without a shared standard,
+each application ends up inventing its own ad-hoc format, which quickly leads to inconsistency and confusion. [RFC 7807 —
+Problem Details for HTTP APIs][rfc7807] solves this by defining a simple, extensible JSON structure for error messages.
+
+**Problem4J** brings this specification into the Spring ecosystem, offering a practical way to model, throw, and handle
+API errors using `Problem` objects. It helps you enforce a consistent error contract across your services, while staying
+flexible enough for custom exceptions and business-specific details.
