After receiving some good feedback on my first question, I decided to edit my question to incorporate the advice with the idea to create a copy-pasteable "final version" for future visitors. However, I learned from comments that such edits are not recommended based on this Meta discussion.
It might be helpful to new users to explicitly mention that editing your question to address feedback is discouraged in the community tour.
A lot of things would be helpful to new users to explicitly mention in the tour... the whole entire Help Center would be helpful!
The thing about answer-invalidating edits isn't specific to Code Review in any way though: Stack Exchange being a Q&A concept (as opposed to a discussion forum concept), as described in the tour, rather implicitly implies that editing answered questions to turn them into impossible-to-follow discussions, is frowned upon.
The specific bit about answer-invalidating edits can be found on /help/someone-answers.
Except some site-specific images, the tour is essentially the same for all SE sites, as it's more about the mechanics of how Stack Exchange works, than it is about the site-specific rules you can find in the help center.
That said, mucho kudos for taking the tour!
