* Check escaping: Double quotes inside JSON values need to be escaped (`"`). HTML attributes using double quotes need to be escaped or I can use single quotes for HTML attributes inside the JSON string to avoid excessive escaping, but the prompt says "Preserve HTML structure". The original uses double quotes for attributes. I must escape them for valid JSON.
*Self-Correction on JSON Escaping:* Since the content is HTML, it contains double quotes (e.g., `border="1"`). In a JSON string, these must be escaped as `"`. Alternatively, I can ensure the JSON is valid. I will escape all internal double quotes.
*Wait, one more check:* The prompt asks to respond IN JSON. I need to make sure the output is *only* the JSON block, no markdown code fences around it? Usually, "Respond in JSON" implies a code block or raw JSON. I will provide raw JSON text to be safe, but often wrapped in markdown for clarity in chat interfaces. However, strict JSON response means no markdown ticks if possible
