Basic i-Radio Button Questions
This demonstrates the basic i-radio fragment system with flag-based answer validation.
Visual Behavior

- On click: Button turns green (correct) or red (wrong)
- Other buttons: Reset to soft outline state when a new answer is selected
Example 1: Simple Binary Choice
Which programming language are we learning?
Example 2: With Always-Visible Comment
What is 2 + 2?
The last item without a flag is always visible as a comment.
Example 3: Multiple Correct Answers
Which of these are even numbers?
Multiple answers can be marked as correct (flag 20).
