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 only, no extra text.

Constraints: summary must be 180-250 words total, split into 3-4 paragraphs separated by \n\n (double newline). Each paragraph 45-65 words. Must bold some key details using ** double asterisks, 3-5 bolded terms across entire summary. Must not bold generic words. Must end with concrete statement, not forward-looking platitude. Must not use banned vocabulary etc. Must avoid AI style.

We need to extract entities: companies, people, locations. From source: Xiaomi, World Power Consortium (WPC), Android Central, ITHome, 9to5Google, Google, Samsung, Nickolas? Person? Probably Nickolas (maybe author). Also location: Beijing, China. So key_entities: companies list includes Xiaomi, World Power Consortium, Google, Samsung, Android Central? Possibly ITHome (but it's a publication). People: maybe Nickolas (author). Locations: Beijing, China.

primary_keyword: likely "Qi2 50W wireless charging" or "wireless charging 50W". Must be 2-3 words. Probably "Qi2 50W". That's 2 words? Actually "Qi2 50W" is two tokens but includes number; it's okay. Could be "wireless charging". But primary keyword should be most important 2-3 word phrase. I'd choose "Qi2 50W". That's 2 words? Actually "Qi2" and "50W" are separate but maybe considered phrase "Qi2 50W". Could be "wireless charging 50W". That's three words. Let's pick "wireless charging 50W". That's three words.

secondary_keywords: 3-5 relevant keywords: "Xiaomi", "World Power Consortium", "Qi2 standard", "50W charging", "wireless charging speeds". Provide list.

content_type: likely "news". Because it's about announcement/meeting.

Now summary: Must be 180-250 words total across 3-4 paragraphs, each paragraph 45-65 words. So total 180-250 words. Let's aim for 4 paragraphs of ~50 words each = 200 words.

We need to bold 3-5 key details across ent
