I spent a total of 2 hours 30 minutes setting this up and then correcting a lot of mistakes, a lot of assumptions, so I would say that the amount of time versus the output that I got at the end is well worth it. Some were my fault, some were outdated files, and a couple of critical mistakes where Claude decided to make things up.
However, if you do not have a brand marketing page or style, then this is a great place to design and develop one.
