/**
 * The immunization-log spec's account hygiene.
 *
 * `vaccinations.spec.ts` asserts GROUPED verdicts — a combination dose appears
 * in each of its three component groups, one antigen holds at most one minted
 * booster reminder, a logged next dose moves the reminder's due date forward.
 * Every one of those is a count over the seeded e2e user's live rows, so the
 * spec has to own the rows it counts against: a dose left by an earlier run, a
 * Playwright retry, or a second project sharing the account would leave a
 * stale group on the page and a second reminder in the antigen bucket, and the
 * grouped assertions would read the wrong count.
 *
 * The reset is delete-then-assert-clean, keyed by the seeded user's id. Links
 * go first for their foreign key; the minted booster reminders go last and are
 * scoped to the ones this feature writes — `vaccination_antigen IS NOT NULL` —
 * so an unrelated Vorsorge reminder another spec relies on is never touched.
