Classification: story; source kind: story; decision: approve; confidence: high; review status: needs-review.

Rationale: A browser membership story with substantive criteria and edge cases, not new-account signup. A local design-correction note introduces unresolved single-account confirmation behavior but does not turn the whole record into a delivery log.

Review qualification: Uncertain identity/behavior/duplication remains a separate candidate; do not merge without review.

Canonical target (to be published after manifest): Proposed canonical target
