Twin Score rubric

A Twin Score is two editorial numbers from 0 to 100, not a five-star widget with a made-up rater count. Scores are editorial 0-100 composites, not star averages and not user-count ratings. AggregateRating in JSON-LD is emitted only for these staff scores. JSON-LD AggregateRating, when present, is those staff scores scaled to 5, with reviewCount equal to editorial reviews — never a fake user total.
