 * Restraint is the point: near-black rather than #000, off-white rather than

 * a failing gate). Everything else is greyscale, so the accent still means
 * something when it appears.
 *
 * Three type roles and no more: a serif for display, a grotesk with tabular
 * figures for every number, and a mono eyebrow. Numbers never get the serif;
 * that is the tell that makes data read as prose.
