We need to produce JSON with fields:

- seo_title: rewritten unique title under 60 chars, different from original headline, include main keyword (maybe "Mexico City security" etc). Must be under 60 characters.

- summary: three or four paragraphs, each 55-75 words. Wait earlier requirement: "Each paragraph should be 55-75 words." But also "split your summary into EXACTLY 3-4 paragraphs" and "Each paragraph should be 55-75 words." The user said "MUST contain at least 180 words". So 3 paragraphs of 60 words each = 180. That's fine. We need 3-4 paragraphs. Let's aim for 3 paragraphs, each 60 words (total 180). Must be exactly 180-250 words total.

- key_entities: list of companies, people, locations mentioned in source. Must include only those explicitly mentioned. Let's identify:

Companies: "ESPN" (source), maybe "Mexico City" not a company, but "Mexico City Mayor", "Mexico City Secretary of Public Security", etc. Actually companies: maybe "Mexico City" is a location, not a company. The source mentions "Mexico City" multiple times. "Mexico City Mayor Clara Brugada", "Mexico City Secretary of Public Security Pablo Vázquez", "Mexico City Secretary of Government César Cravioto", "Mexico City Secretary of Civil Protection Myriam Urzúa". These are positions, not companies. "The Associated Press" is a news agency, could be considered a company. "ESPN" is a company. Also "The Associated Press" is a news agency. "Mexico City" is a location. "Estadio Azteca" is a location (stadium). "Paseo de la Reforma" is a location. "Zócalo" location. "Santa Fe area" location. "Guadalajara" location (mentioned). "Ecuador" location (country). "Mexico" location. "England" location (team). "Mexico City" etc. But we need only companies, people, locations. Companies: ESPN, Associated Press. Also maybe "Mexico City" is not a company. "Mexico" is a country. "England" is a country. "Guadalajara" is a city (location). "Estadio Azteca" is a stadium (location). "Paseo de la Reforma" location. "Zócalo
