/* Nadir — visual language
 *
 * Dark, quiet, precise. Near-black ground, one indigo accent used sparingly,
 * hairline borders instead of boxes, and a lot of vertical air. Type is tight
 * and slightly negative-tracked at display sizes; everything secondary drops
 * to a muted grey rather than a smaller size.
 *
 * One page for now — downloads. Nothing here styles anything that no longer
 * exists.
