/**
 * Zen, said once. Every page that names a Zen generation reads it here —
 * /models, /zen, /zen/models, the family cards, the Research menu and
 * /research-access — so no two of them can disagree about which generation
 * answers, which came before it, which is next, and what it is for.
 *
 * Zen 7 is @hanzo/ui's `RESEARCH` entry, the one the model pickers list, so a
 * page and a picker cannot disagree about it either. Its request link is an
 * absolute address there, because the pickers run on other hosts; here it is
 * this site's own path.
 *
 * Zen is named as Zen: see lib/upstream for what the copy never says.
