This challenge looked deceptively simple, but I really puzzled over it a lot! I tried several different approaches. The code I have here is what I came up with while live on Twitch, but it only got me to 99.9%. I was previously able to get 100% using clip-path to define the entire shape. With clip-path I had to define 16 different (x,y) coordinates and fiddle with nearly every one of them a few times to get it right.
