What is the best way to customize rendering of Markdown styles, in both UIKit and Swift? For instance, how should I tell it what font to use for normal and Bold text? This is what kept us from using NSAttributedString+HTML for embedded string formatting in the past, and AttributedString+Markdown looks even better for this use case, so I'm hoping the fact that we use a custom font won't be a roadblock. Is calling .replaceAttributes() the expected pattern, and just doing this for each expected attribute in each string?
