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

We must produce a summary of the source article, 180-250 words total across 3-4 paragraphs, separated by \n\n in the summary string. Paragraphs each 45-65 words. Must bold a few key details (3-5 total across summary) using **. Must not overdo.

We must also include key_entities with companies, people, locations arrays containing only those mentioned in source. The source mentions people: Iga Swiatek, Taylor Townsend, Amanda Anisimova, Katerina Siniakova, Naomi Osaka, Marion Bartoli, Karolina Pliskova, Lina Gjorcheska, Jasmine Paolini, Robin Montgomery. Also maybe "BBC Sport". Also "Royal Box". Locations: Wimbledon, Centre Court, Royal Box. Companies? Not many; maybe "BBC". Could include "BBC". Also maybe "Wimbledon". But categories: companies, people, locations. So companies: maybe "BBC". People: list all names. Locations: "Wimbledon", "Centre Court", "Royal Box"? Probably just "Wimbledon". We'll include relevant.

We must also include expert_faq with 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 additional relevant keywords/phrases.

content_type: likely "news". Must be one of allowed values: "article|news|guide|review|comparison". Choose "news".

We must ensure JSON is valid, no extra formatting, no markdown. Must output only JSON.

We must count words in summary: 180-250 words total across all paragraphs. Paragraphs 45-65 words each, 3-4 paragraphs. Let's aim for 4 paragraphs of ~50 words each = 200 words.

We need to bold 3-5 key details across entire summary. Choose: Iga Swiatek, Taylor Townsend, Wimbledon, maybe BBC Sport, maybe Karolina Pliskova. That's 5 bolded terms. Must bold only those specific terms, not generic words. Use double asterisks.

We must not bold gener
