 *
 * One stylesheet, no framework, no webfont request.
 *
 * The look is warm editorial rather than product marketing: paper and ink, a
 * serif for anything a person wrote, and colour reserved for the one thing it
 * has to mean — an extension's status. What earns its keep beyond that is
 * structure: a hero that gives the page a beginning, a facts panel that stays
 * with you while you read, and the score drawn as an object rather than stated
 * as a number.
 *
 * The headline face is a system serif stack. It costs no request and still
 * gives every page a voice.
