// R-497 — the „Tulajdonosi jelmondat" is delivered by NOTHING in the product: it is minted at customer
// creation, shown only on the operator's customer page, and never e-mailed (the operator has not ruled
// that e-mail may carry it). Measured 2026-09-14 in the first-hour drill: the self-bind mail told the
// customer they had received it „a beállításkor" — true only if the operator remembered to hand it over,
// and nothing told the operator to.
//
// These pin the CONSEQUENCE, not a string for its own sake: the operator is told at the moment the
// phrase exists, the page repeats it where the phrase is shown, and the customer's mail names the person
// they got it from. The last test pins what must NOT change — the mail still carries no phrase.
