Fixing a few hundred clear typos with the help of Claude. Some are less important in code comments, but majority of them are in user-facing places. I manually approved 60%+ of the changes and didn't see any that were an incorrect suggestion, at worst it was potentially uncessesary, like a code comment having cant instead of can't. No RM.
