If amount is smaller then minted how to transfer?

[0xCardiE]

With this code here

ERC404/src/ERC404.sol

Line 215 in 14c1362

if (amountOrId <= minted) {

you enforce that if amountOrId in transferFrom is smaller than minted it will try to transfer NFT.
But what if I want to transfer less than 10k amount, for example I want to transfer 1000 amount and transferFrom is called, how will I transfer that tokens when it will keep going to the first part of condition and fail there?

I think it makes more sense to use [type(uint256).max / 2, type(uint256).max] bounds for tokenIds. And reserve [0, type(uint256).max / 2) domain only for ERC20 amount encoding. This way implementations will still be able to use up to 255 bits for storing ERC20 amounts, which is more than enough for most projects.
