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

We must produce a summary 180-250 words total across 3-4 paragraphs, separated by double newlines. Each paragraph 45-65 words. Must bold 3-5 key details across entire summary, using double asterisks. Must not bold generic words. Must include specific facts from source: Samsung upcoming Galaxy Z foldables, leak details cameras, models: Galaxy Z Fold8 wide, Galaxy Z Fold8 Ultra, Galaxy Z Flip8. Specs: Ultra retains triple rear camera setup but replaces 12MP ultrawide with 50MP sensor; keeps 200MP ISOCELL HP2 primary and 10MP telephoto; Fold8 wide has dual rear camera two 50MP sensors; has 10MP selfie on cover display and another 10MP on inner screen; Flip8 retains same camera hardware as Flip7: 50MP primary and 12MP ultrawide. Launch expected July 22, sales start Aug 5. Also mention dummy units image maybe not needed. Must bold 3-5 key terms: perhaps Galaxy Z Fold8 Ultra, 50MP ultrawide, July 22, August 5, 200MP primary. Choose 3-5. Must be selective, not per paragraph. So across summary, bold maybe Galaxy Z Fold8 Ultra, 50MP ultrawide, July 22, August 5, 200MP primary. That's 5. Ensure only those are bolded.

Word count: 180-250 words total across paragraphs. Paragraphs 45-65 words each. If 4 paragraphs, each ~50 words => total ~200 words. Good.

We need to output JSON only, with fields as described. Must include key_entities with companies, people, locations. Entities in source: Samsung (company), maybe "GSMArena" as source but not entity? Entities: companies: "Samsung"; people: ; locations: maybe none. Should include only those explicitly mentioned. So companies: "Samsung"; people: ; locations: .

expert_faq: question and answer based on article content. Must be 30-50 words answer.

internal_link_anchor: 2-4 word topic phrase.

primary_keyword: single most important 2
