The deck-as-article output now reads like a serialized column: one 680px reading measure, a paper-first hero (series kicker → title → lead → meta chips), and per-slide blocks — number, small-caps section label, headline, hairline-framed slide, then the narration as prose. Optional per-slide reference links roll up into a deduped end-of-article list.
New optional keys: series / lead on the deck manifest, label / refs on any slide spec. Attached: the rebuilt demo-article.html.
