Do you use Shadcn CLI or Copy-Paste?

I was wondering how you guys use shadcn and why. Do you also adapt the components/tailwind config/theming/animations or keep it as it is?

I personally have strong opinions on how I structure things and i like to add my own version of tailwind theming and variables. However, I dont want to develop a footgun, which makes it harder for me to add with updates etc.
