 * Every colour here is a token from tokens.css. No literal values.
 *
 * The ground is ink and the artwork sits on it in framed plates. An earlier
 * version tried to match the page to the cream the artwork carries, which
 * cannot be done: the artwork is about six levels lighter at its top than at
 * its bottom, so any flat ground matches one edge and misses the other, and
 * a near miss reads as a mistake. Contrasting deliberately and drawing a
 * hairline round the plate says the edge is meant to be there.
 *
 * There are no shadows. Depth is a hairline on a flat ground.
