Added comprehensive inline comments (mainly in German) to key files (index.html, Program.cs, App.razor, MainLayout.razor, NavMenu.razor, Catalogs.razor, CatalogApiClient.cs) to clarify their roles and the overall application flow. Updated Home.razor with a clearer heading and intro. Introduced Ablauf.cs, which documents the loading order and responsibilities of each major component. These changes enhance codebase clarity and maintainability, especially for German-speaking developers.
