/**
 * The institutional mark is the real crest, on every surface.
 *
 * The renderer used to substitute a single-colour knockout on dark or strongly
 * coloured grounds. It is the owner of the mark who decides that, and the
 * decision is that the crest is never rendered black or white — a flattened
 * silhouette reads as a stamp, and a mark that changes slide to slide reads as
 * a mistake. This pins the loader's shape so the variants stay available to an
 * identity that asks for one by path.
