@Rich-Harris out of curiosity: why is device pixel ratio the only one that doesn't use ReactiveValue?

[Rich-Harris]

Because there's no event that you can listen to, we need to track it with a media query that changes from true to false to indicate that it changed. But once that happens, the media query is no longer useful and we need to create a new one. You can't do that with createSubscriber because you can't create a new subscriber inside an old one

Uh I just noticed the interpolation in the media query...that's a pretty fucked up API lol
