/* Custody Roundtable
 *
 * One rule carries the design: gold means a name is attached to it. Named
 * people, signed replies and roundtable attribution are gold. Structure,
 * numbering and status stay grey. The project's editorial rule is that every
 * branch carries a named attribution, so the names are the brightest thing on
 * the page.
 *
 * Monospace is the structural face, for node numbers, pillars, status, keys
 * and timestamps, because this content genuinely is hex, paths and keys. The
 * arguments themselves are set in sans at a readable measure.
 *
 * The spine, a hairline with square markers, carries position in the tree.
