+///
+/// This view provides a form interface for users to input todo task details including:
+/// - *Title* (required)
+/// - *Note* (optional)
+/// - *Due date* (required)
+///
+/// The view uses a dedicated view model (`ViewModel`) to manage state and business logic, following the MVVM pattern.
+/// When the user saves, the todo is inserted into the SwiftData model context and the view is dismissed afterwards.
