 * Art direction: a game engineer's editorial portfolio.
 * Graphite canvas, solid slate surfaces, and clear ivory typography. Amber
 * identifies primary actions, ice blue supports technical detail, and green
 * accompanies a release label. Actual gameplay supplies the rich color.
 * Space and fine borders carry the hierarchy; motion is brief and deliberate.
