How do you deal with dynamic classes ?

I found out that using dynamic classes requires you to add the given class to the safe list as Tailwind is only loading classes statically present in the className attribute. As this is obviously heavy for maintenance (if you want to keep the size optimised, stripped from unused CSS), how do you deal with this ? Here is an example, how would you make classes static ?

const Button = ({variant}: {variant: 'green' | 'blue'}) => {
  return <button className={`bg-${variant}-500`}>Click me</button>
}

const Button = ({variant}: {variant: 'green' | 'blue'}) => {
  return <button className={`bg-${variant}-500`}>Click me</button>
}

OK, I didn't find this page from the doc which is exactly about the issue: https://tailwindcss.com/docs/content-configuration...

const variantToClass = {
  'green': 'bg-green-500',
  'blue': 'bg-blue-500'
}

return <Button className={variantToClass[variant]}/>

const variantToClass = {
  'green': 'bg-green-500',
  'blue': 'bg-blue-500'
}

return <Button className={variantToClass[variant]}/>

And what if you mixes different variants ? Let's say you add to this button an inverted mode ? Interesting, thank you, is that what you use?
