/* The Road to Superintelligence — 1965 to the White House Accord.
 *
 * Shares the paper, type and sidebar of the other AI timelines (built from
 * Rise of the Personal Agent's stylesheet). Each band has one hue (ideas
 * violet, labs rust, rules blue, machines green) and is also named in text;
 * an event's kind is carried by its shape, so the page reads in grayscale.
 * The Accord itself is gold.
