GJ one your library

One random recommendation I could give based on my experimentations on both firefox and chromium

you can attach symbol based custom properties to each such dom node 'class'

and apart from using .matches(), symbol attribute check. this outperforms class based equality checks by a small margin.

very marginal but hey, you are clearly tryharding.

Thank you! Very interesting insight—I'll have a look.

thanks, I can not make it public since it accesses AI endpoints and stuff. you can use the credentials though. username:ppl password:12345
