  const isMatch = React.useMemo(() => hash === crushHash, [crushHash]);

Sure is a lot of work to do a string comparison 'efficiently'.

Definitely a waste. `useMemo` has a bunch of performance issues related to it and should only be used when absolutely necessary.

That's mad because the useMemo clearly has to do an equality check to see if it changed anyway...
