How this layout works
The full-widget layout flips the usual order: the interactive component renders first at full width, and any markdown prose you write here appears below it as supporting context.
Use it when the widget is the lesson — and the text is just there to explain the controls or interpret the output.
When to choose full-widget vs topic
Choose topic when the prose sets up the concept and the widget is a bonus exercise at the end. Choose full-widget when you want learners to interact first and read second.
