I practised identifying an enclosure that was not fully seated and following the demonstrator's hold instruction. I was slower than the review makes me sound, but I could explain the second example without a prompt.

Keep that example and name the help. Does the title repeat the quick-setup claim?

It did. Title and opening now describe a supervised session at a prepared station, and the seating example explains both the prompt and my later attempt. Thank you, Henry. The corrected account is still positive, just more useful.
