Yeah, our official Python client supports highlighting, but in a much simplified manner: just placeholder content is emphasized (without respect of the kind of it).
python color code:

I think that a proper parser can be written to process placeholders. We already have tldr-lint, check it out how pages are analyzed for smells, maybe you find smth useful. But for the beginning regex based highlighting can be used. This is how tldr client for Emacs works AFAIK.

TODO
- decide a highlight color theme with light and dark mode
- replace more syntax
- find a style for mnemonics
- customize color
To achieve better synatx highlighting, we need to parse the markdown by ourself as well. marked.parse only returns raw html which doesn't quite compatiable with vue. As a result, some functionalities such as copy to clipboard cannot be implemented.
