Like, you wanted something with very exacting formatting, called a "hypernote". You could just create a .css with a style called "hypernote" and give that to the devs to integrate into their default .css.
Then, you would just need to create a 30041 including the .adoc tag "hypernote" and it would render in HTML, the way you'd defined it. It would use a Nostr Asciidoc event to generate hypernotes on the fly, without storing HTML in the events.
