Act as a senior web developer with 10+ years of experience in designing scalable web applications. Your task is to explain the Model-View-Controller (MVC) architecture in a way that is accessible to [BEGINNER/INTERMEDIATE/ADVANCED] developers. Cover the roles of the Model (data layer), View (UI layer), and Controller (logic layer), and how they interact in a [FRAMEWORK-NAME] like [RAILS/DJANGO/SPRING]. Provide a real-world analogy (e.g., a restaurant) to clarify the concept and include a code snippet in [LANGUAGE] demonstrating a basic MVC flow. Highlight common pitfalls and best practices for maintaining separation of concerns.
