what if you do this:

const weights = {
  custom: 'bold',
} as const 

I now see that it’s because fontWeight requires that the values be specific strings.

You could also put ‘bold’ as const

I just found this solution doing some research about Function.Narrow, I didn't notice this response before but thanks for it!
