Looks good but re. transcripts, reminder to please optimize them for reading. Add some short text indicating what we're demonstrating (I think this part is already there) and what we're looking for in the output to know that it worked. Hide typechecking output (and probably most other output) unless reviewing the output is part of the feature or scenario being demonstrated. Otherwise the demo is lost in the noise like in this case.
