code highlighting and WYSIWYG thoughts

[vezwork]

1. Vscode/monaco themes are the same as “text mate themes”
2. Textmate themes are very expressive (although still depend on how languages annotate spans on code blocks), its probably possible to convert themes from other theming systems into text mate themes, but not vice versa
3. I want WYSIWYG to be possible (editor looks identical to rendered) and using text mate themes with Monaco for editing and e.g. Shiki for rendering would work. Alternatively, If we want true WYSIWYG we could render code blocks using non-editable monaco editors, although that would be sort of wasteful of people's computational resources.
4. In general, I advocate for us to think about how renderable things can be edited and to put that rendering and editing tech into user space so we can make it user customizable and extensible
