/**
 * /ZEN TELLS THE WHOLE STORY, AND EVERY NUMBER ON IT HAS A SOURCE.
 *
 * The page opens on its painting and the release's name, then markets two
 * releases, the one that answers and the research preview, each a card with its
 * name large; every earlier Zen model is a link to its own page under /models.
 * Then a run of short headlines, each with the content that backs it: the open
 * lineage, the three machines Hanzo measured, what the board scored, and the
 * one call that reaches it. Held
 * at every width the site designs for, with motion on and with it off — a
 * reduced-motion reader gets every word and every figure, finished.
