 * It lives in a first-party cookie on the registrable domain because localStorage
 * is ORIGIN-scoped: docs, cloud and console each minted their own id for the same
 * person, so one marketing → docs → signup → checkout journey arrived as several
 * strangers — 463 anonymous identities carried 545 events in a week, about 1.2
