In the real world, there are any number of ways to distinguish style from formatting, but on Meta.EL&U, neither has been specified in the tag wikis. They are both a jumble of questions about which type of formatting to use to represent different elements in a post, about how to indicate such formatting in Markdown, about SE changing the visual presentation of those elements, and about tone and writing style.

Neither formatting nor style is heavily used, each with 15–16 posts. Therefore, I propose merging them as style with formatting as a synonym, followed by cleanup relegating a few questions to design and others.
Alternatively, a case can certainly made for keeping them distinct, but as they are currently used almost interchangeably, I suspect it may not be worth the upkeep on a relatively small number of questions.
