/*
 * Marketing site.
 *
 * A quiet, centred, editorial look: near-white ground, a serif display face for
 * headings against a plain sans for everything else, generous vertical rhythm,
 * and soft rounded cards with almost no shadow.
 *
 * Fonts are system stacks on purpose. A webfont would mean an external request
 * and loosening the content security policy, and the serif/sans contrast is
 * what carries the look rather than any one typeface.
