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

Constraints:

- Summary 180-250 words total across 3-4 paragraphs, each 45-65 words. So 3 paragraphs of ~60 words = 180 words. Or 4 paragraphs of ~50 = 200. Must be within 180-250.

- Must bold 3-5 key terms across entire summary using double asterisks. Not too many.

- Must not use banned vocabulary. Avoid filler.

- Must not end with forward-looking platitude.

- Must include key_entities with companies, people, locations only from source.

- mentioned. Source mentions: Bending Spoons, Evertale, AOL, Eventbrite, Vimeo, Evernote, Issuu, Harvest, Baillie Gifford, Nasdaq, Milan, Copenhagen, Indonesia, Denmark? Actually Copenhagen is location. Also London? The article by FT in London. But only entities mentioned in source. We'll include companies: Bending Spoons, Evertale, AOL, Eventbrite, Vimeo, Evernote, Issuu, Harvest, Baillie Gifford (investment firm), Nasdaq (exchange). People: Luca Ferrari, Matteo Danieli, Francesco Patarnello, Tomasz Greber, Luca Querella, Florinda Pannofino, Joe Hyrkin. Locations: Milan, Copenhagen, Indonesia, New York (Nasdaq Market Site), London (FT). But maybe only those explicitly mentioned. We'll include.

- expert_faq: one question and answer 30-50 words.

- internal_link_anchor: 2-4 word topic phrase.

- primary_keyword: single most important 2-3 word phrase.

- secondary_keywords: 3-5.

- content_type: likely "news" (breaking timely) or "article". Since it's a news article about IPO, choose "news".

- seo_title: rewritten unique title under 60 chars, different from original headline. Must include main keyword.

Original headline: "How Bending Spoons built a $23bn tech empire from struggling brands". We'll rewrite: "Bending Spoons' $23bn IPO fuels acquisition spree". Count chars: "Bending Spoons' $23bn IPO fuels acquisition spree" length? Let's count: Bending(7) + space(1)=8, Spo
