The OFFLINE cohesion silhouette: embed each body section and measure how alike
they are. A low mean pairwise cosine means the article's sections have drifted
into distinct topics — a structural split signal the word-size heuristic can
miss. This is the SANCTIONED offline use of embeddings; embed is injected and
MUST NOT be the read/route path. Pure aside from the injected embed.
