Typecraft's baby log has been mostly well-kept… until a sleep-deprived 3AM entry and a couple voice-to-text dictations gone wrong. Now the pediatrician’s email parser is rejecting the log due to "inconsistent formatting." Your task is to clean it up and convert it into CSV.

Fix it in five minutes or suffer a 200-slide Lunch 'n Learn on our release process.
