/* Memo — a theme stylesheet for a long argued document (spec §6).

 *
 * A newspaper-ish register: a display sans for headings, a serif for reading,
 * a mono for anything that is a label, a number or a citation. The document
 * names none of this. It names roles (.marker, .claim, .change, .facts, .quote)
 * and this file decides what a role looks like.
