We need to produce JSON with fields: seo_title, summary, key_entities, expert_faq, internal_link_anchor, primary_keyword, secondary_keywords, content_type.

Word count: summary 180-250 words, split into 3-4 paragraphs, each 45-65 words. Let's aim for 4 paragraphs of about 55 words each => total 220 words. Must be 180-250 inclusive.

We need to bold 3-5 key details. Must be selective. Bold only key entity, critical figure, important fact. For example bold "Spud Cell", bold "University of Minnesota", bold "$2tn to $4tn", maybe bold "Mc Kinsey". But need 3-5 bolded terms total. Let's choose 4: Spud Cell, University of Minnesota, $2tn to $4tn, Mc Kinsey. Ensure they are inside summary paragraphs. Must be exactly 3-5 bolded terms across entire summary. We'll include 4.

Now count words. Let's draft paragraphs.

Paragraph 1 (45-65 words). Content: Scientists unveiled synthetic cells called Spud Cell, designed to act as tiny biological factories for low‑carbon manufacturing. The invention, built from non‑living chemicals, completes a full cell cycle of feeding, growth and reproduction. It will be shared globally, marking a shift toward micro‑scale bioengineering in industrial production.

Let's count words. We'll count manually.
