Hi, there used to be a style guide or brand library that was publicly available, but I don’t think it exists anymore. We’ve been using the same approach you mentioned — reverse-engineering and applying the same classes used within the edit/settings UI.

Not exactly what you're asking for, but these two posts might be helpful?

It's just a big headache to borrow Opti's frontend stuff IMHO.
Customers I work with have been fine with just a top bar with a back to CMS link and then author your own plugin views with Tailwind CSS.

We're developing a bunch of custom addons (to be used in the CMS admin). It looks "OKish", after having reverse-engineered the built-in razor views and made some qualified guesses.
But we would really like to do this "by the book". However, we have a hard time finding the book...
Are there any documentation on how to build custom razor views that align with the look and feel of the Optimizely backoffice? Examples of what layout setting there are, what styles and scripts should be included, how we should mark up our elements, any built-in widgets/selectors, table styling etc.
We're on CMS 12+
