/*
 * The mock Agent Marketplace and Catalogue.
 *
 * One rule governs colour, and it is the same rule the rest of the demonstration uses: colour marks
 * WHO OWNS a thing, never how far along it is. Cyan is CBA side, which is everything this app owns.
 * Gold is Raidiam product, which is everything the Trust Controller owns. A panel painted gold on
 * this site is a panel this app is only reporting, and cannot change.
 *
 * State gets its own three colours and none of them is either accent: mint means passed, rust means
 * refused, grey means never asked.
