It's ~90% copied from their CSS, I had to make a few adjustments sometimes. I used my own tool (CSS Scan - https://getcssscan.com https://getcssscan.com) to copy the CSS. The only buttons made from inspiration were the ones from the macOS Big Sur (number 10, 11, and 12). Also, a few buttons used JS to change styles according to the cursor and I had to remove this part.
