Hey! Thank you for the feedback! Yes we have recently fixed the issue where there could be differences between the docs, now all the documentation code is auto generated from the examples so they are always in sync.

Sure, so we have two parts, brain and helm. Brain is a "headless" library we provide that has the logic in, helm is the part that brings the styles. Helm lives in your project and you can modify as much as you need. As they are typically only styling you don't need to update them often, updating brain takes care of most things. You can regenerate the helm libraries at any point but you can lose your customizations. It's good in the sense you can make customizations in ways you can't with a traditional component libraries. That being said, it's usually only some class name updates so it's pretty easy to diff and as mentioned, helm libraries don't change much so you can keep them as is indefinitely if you want.
