Finally, format the JSON correctly, ensuring proper syntax. No extra keys. Use bold and italics as specified. But in the JSON structure, the content is just text. Wait, the user mentioned using word for bold and word for italics. But in the JSON example, the content is just strings. So perhaps the bold and italics are not needed here. Wait, looking back at the output format example, the user says "Use word for bold" and "Use word for italics". But in the JSON structure, the content fields are plain text. Hmm, maybe the user wants the JSON to include markdown formatting within the content strings. For example, in the content of a paragraph, use bold or italics as needed. However, in the example provided by the user, in the base JSON structure, the content is just a string. So perhaps I need to include markdown formatting within the content strings. Let me check the user's example again. The user says: "Base JSON structure: { 'content': [ { 'type': 'paragraph', 'content': 'Paragraph text' } ] }". So the content is a plain text string. Therefore, any bold or italics would need to be included as markdown within the string. However, in the sample output provided by the user, they have the paragraph content as a string, but they didn't use any markdown. Wait, the user says "Use word for bold" and "Use word for italics", but in the JSON output, the content is a string, so those markdown elements would be part of the string. But in the example, there's no markdown. Maybe the user wants to include the markdown in the JSON. But the example given by the user in the problem statement doesn't have any. Hmm, this is a bit confusing. Let me re-examine the user's instructions. The user says: "Output Format (Exact): Return only the Competitive Landscape content with: 2 paragraphs then 6 bullet points. No extra text before or after. IMPORTANT — OUTPUT CONTRACT (STRICT) Return ONLY raw JSON wrapped in a Markdown code block. Formatting rules: Use word for bold Use word for italics Do NOT use HTML tags". So the JSON content should have the actual markdown within the strings. So in the paragraph content, if there's a word to be bolded, it should be word, and italics as word. However, in the sample output provided by the user, they didn't use any. But the user's example shows that the content is just a string. So perhaps the user expects that if there's a need to bold or italicize, include the markdown in the string. However, in our case, the user didn't mention any specific words to bold or italicize. The only mention is for including the SEO phrase naturally. So maybe in the first paragraph, the SEO phrase "Cardiovascular Ultrasound key players" should be in bold. But the user says to include it naturally. Wait, the user says "Include one SEO phrase naturally: 'Cardiovascular Ultrasound competitive landscape' OR 'Cardiovascular Ultrasound key players'". So perhaps just include it in the text without bolding unless instructed. The user's example in the problem statement includes the SEO phrase in the first paragraph without any formatting. Therefore, perhaps the JSON content should not include any markdown unless specified. The user's example shows that the content is plain text. Therefore, the correct approach is to include the SEO phrase as part of the paragraph text without any formatting.
