All the more reason to have a cheat sheet that shows what it'll look like once it is finally rendered by the client.

You missed the point. A cheat sheet would show what it'll look like rendered by your client. To judge how it would be rendered for others, the text description of a tag is as good as it gets.

But feel free to come up with such a cheat sheet. Experiment on repellent's scratchpad, then if you like the result, post it in this section.
