It's part of the reason I'd waited so long before making this, I knew it was going to be a lot of work. There's parts that Claude was especially useful for, like perf testing, debugging and animation. But the first half of the project was done almost entirely by hand.
I have complex feelings about it all too. My hope is we'll re-consider what's considered hard. As a designer who started his career after the advent of digital typesetting, some of the things I barely think about were once considered difficult.
Human effort as a proxy for quality... that ship has sailed. And that makes me feel frustrated.
