/* Underline on hover belongs to prose links only.
 *
 * `article a:hover` used to be in this list and was the reason card chrome —
 * tag chips, "Read article", the repository/article/visit/details row on a
 * project card — underlined under the pointer. Every card, row and system
 * card is a `document.createElement('article')` (content-runtime/43-blocks),
 * so that selector matched all of their links and none of their prose.
 *
 * It was not earning its place even for prose: an article or post body
 * renders into `<div class="article-content">` inside a `<section>`, never
 * inside an `<article>`, so `.article-content a:hover` is what actually
 * underlines editorial links. Dropping `article a:hover` therefore removes
 * the card underlines without touching a single prose link — and retires the
 * `article h2/h3 a:hover` exception that existed only to cancel it for card
 * titles, plus the chip exceptions that were being added one class at a time
 * as each new piece of card chrome turned up underlined. */
