Unclear for the Shifting 96, address owner = address(tokenId >> 96);

[itdream-dev]

function mintAndTransfer(LibERC721LazyMint.Mint721Data memory data, address to) public override virtual {
address minter = address(data.tokenId >> 96);

....
function _mint(address to, uint256 tokenId) internal virtual override {
require(to != address(0), "ERC721: mint to the zero address");
require(!_burned(tokenId), "token already burned");
require(!_exists(tokenId), "ERC721: token already minted");

    _beforeTokenTransfer(address(0), to, tokenId);

    _holderTokens[to].add(tokenId);

    _tokenOwners.set(tokenId, to);

    address minter = address(tokenId >> 96);

....

I want to know clearly how it can be minter by the address(tokenId >> 96);

As replied in discord, this is used to save some gas.

Here's a Stack Overflow thread that should clear this out: https://ethereum.stackexchange.com/questions/35097/can-someone-explein-me-this-multi-mint-function-solidity
