The quotation (12 words) matched the card’s text retrieved for the candidate pack on 2026-11-02 (SHA-256 766262a78fcaeae31534174554bae5b259a418eaffbf9f23a9460343943b9d8e) and again on 2026-11-03 in a fresh retrieval with the same SHA-256. Matching ignored differences of whitespace, case, quotation marks, dashes, PDF line-break hyphens and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.
