Description: The blog we run on a customer's own domain. An index of article cards, an article page that is the article and nothing else, and a chrome-less template for mini-apps. No comments, no widget areas, no "about" or "FAQ" footer — every element that isn't the content is one the reader didn't come for.

   their site — not like a different product bolted on. */
