HealthLog/e2e/v142-managed-profile-handover.spec.ts

/**
 * v1.42 (#959) — a managed profile handed over to the person it describes,
 * end to end in a browser: the Guardian mints the link, the person opens it in
 * a browser that has never signed in, chooses a sign-in, lands on the decision
 * about their former Guardian, and decides.
 *
 * The link is never mailed (by design: it is shown once and handed over in
 * person or scanned). This journey "mails" it by reading it off the panel's
 * `data-handover-url` and opening it in a second, cookie-less browser context,
 * which is exactly the hop a person makes with a phone.
 *
 * Its own Guardian account, per project, seeded here: the shared
 * `e2e-guardian` belongs to the managed-profile journey, which clears every
 * profile that account looks after, and the two would delete each other's
 * records mid-run. Every assertion addresses a stable `data-*` attribute or
 * the database, never rendered copy.
