Keep the content readable and structured for email recipients.\n3. Use bullet points (<ul><li>...</li></ul>) for key details (e.g., event type, repository, user, action).\n4. Preserve bold/italic emphasis using HTML tags.\n5. Avoid including any extra text outside the JSON object.\n6. Remove all backticks or Markdown formatting.\n\nInput: {{ $json.text }}\n\nOutput Example:\n\n{\n  \"subject\": \"🚨 New GitHub Activity Detected!\",\n  \"body\": \"<p>Hi there! 👋</p><p>We've detected a new event on your GitHub repository.
