    I was reading this tweet with my morning coffee and thought it could be a fun feature to give claude 4.5 Tbh, I thought it would never make it to prod because it's harder than it seems. For instance, components like this have tons of if/else + gradient effect on hover/click + light/dark mode. But claude did an awesome first shot, I just tweaked a few minor things, and improved the color picker UI. Less than an hour later, it was in prod. Thanks AI Thanks @shraddhac92
