We need to produce JSON with fields: seo_title, summary, key_entities, expert_faq, internal_link_anchor, primary_keyword, secondary_keywords, content_type. Must be valid JSON, no markdown. The summary must be 180-250 words total across 3-4 paragraphs separated by double newline (\n\n) inside the summary string. Each paragraph 45-65 words. Must use active voice, human style, avoid banned words, etc. Must bold 3-5 key details across entire summary using double asterisks. Must end with concrete statement, not forward-looking platitude. Must not use banned vocabulary or filler. Must not use banned closers. Must not use excessive hedging etc. Must not start sentences with same pattern. Must vary sentence starters.

We need to count words precisely. The summary must be exactly 180-250 words total across all paragraphs. Let's craft 3 paragraphs of about 55-65 words each to reach around 180-200 words. Let's aim for 3 paragraphs of 55 words each = 165, need 180-250, so maybe 4 paragraphs of ~50 words each = 200 words. Must be 3-4 paragraphs. Let's do 4 paragraphs of ~50 words each = 200 words total. Each paragraph 45-65 words, okay.

We need to include bold formatting for 3-5 key details across entire summary. Let's bold: England, South Africa, Marcus Smith maybe also appendicitis? But only need 3-5 bolded terms total. Let's bold England, South Africa, Marcus Smith, appendicitis, Nations Championship maybe. That's 5 bold terms. Use double asterisks around them. Ensure they appear in summary. Must not bold generic words. These are key specifics.

We must not bold generic words like "announced". So bold only those.

Now craft summary paragraphs.

Paragraph 1: talk about player out due to appendicitis, mention Nations Championship opener, mention replacement Marcus Smith likely. Include bold terms maybe appendicitis, Marcus Smith, England. Also maybe bold South Africa? Let's decide: bold appendicitis, Marcus Smith,
