I went straight to npmx to check if ?kawaii=true in the URL worked (try it on bsky.app, and some other sites), then to the github to see if someone made an issue/PR yet.
It hasn't been implemented on it in npmx but if someone open an issue on it (which they most likely be okay with), i will be happy to send the .svg and .pngs! Just tag me (alfonsusac) on github.
