/**
 * Shared styling for the map's document pages (about.html, contact.html).

 * These are prose, not dashboard: one centred column, read top to bottom. They
 * take their palette, type and theme tokens from styles.css and only describe
 * the layout a document needs, so a theme picked on the map carries over here.
 *
 * styles.css pins html and body to the viewport with overflow: hidden, because
 * the app is a fixed dashboard that never scrolls. A page of prose very much
