It seems like a situation that would benefit from separating the logical/structural definitions from the layout/presentation rules, much like HTML and CSS. The structural side would be clean and easy to maintain and all the fiddly presentation stuff would have space to be specific. Constraint-based layout rules a la flexbox would seem useful. Has anyone tried that approach?

Edit: You're probably still going to have to render it as part of the review for non-trivial changes but when the visual result matters I don't see any way to avoid that.
