 *

 * alongside its prose sibling — no JS, no absolute positioning.
 *
 * Placement rule: put the marginnote element BEFORE the prose element it
 * annotates. Because both are grid children in the same row-gap:0 grid,
 * the note will be aligned to the top of the adjacent prose block.
 *
 * Variants:
 *   .article-marginnote--def     definition / glossary term
 *   .article-marginnote--source  source / citation
 *   .article-marginnote--figure  thumbnail chart or image
 *   .article-marginnote--callout highlighted aside
 *
 * Below --prose-wide (940px) the margin column collapses and notes
 * automatically pull into the prose column via a media query.
