Making a book with a designer who argues

The sequence that survives an argument is almost always better than the one that does not.

Where it starts

Replace this body with the real piece. Every ## heading is picked up by render() and listed in the contents rail beside the article.

What to keep

Write in plain MDX. Paragraphs, lists, <aside>, <blockquote> and <figure> all pick up their styling from .post-content in global.css, so no classes are needed here.
