Review Comment:
I was also under the impression that case insensitive meant that as long as
the word spells the correct type we don't care what the cases of the letters
are? So currently if someone were to type "cLaSsic" that would still be valid.
If we want to strictly allow only "Classic" and "classic" we would need to
probably add both for each type to the enum itself. Lmk what you think?
