/*
 * An Insights article (single.php), as in the Article wireframe:
 *
 * 1. The heading band on the darkest teal: the breadcrumb, the eyebrow after a teal rule, the title in white, the
 *    excerpt and the byline, with the key date card beside them at the foot. On tablets and phones the card
 *    follows the byline.
 * 2. "In a nutshell" in a pale teal band of its own, when the article has one.
 * 3. The article beside "In this article" and the free call box. On tablets and phones they follow the article.
 * 4. Related articles on pale teal, three side by side, or one above another on tablets and phones.
 *
 * The Explainer layout (insight-article--explainer) is at the end: a light heading with "Myth and fact" beside the
 * title, "Jump to" pills, and the article the full width of the page, its sections as bands.
 *
 * Each band runs the width of the page; the words inside keep to 1200px, centred, so lines stay readable. The
 * ready-made pieces inside the article are styled in assets/css/components/insight-pieces.css.
