Generate a concise, 3-5 word title with an emoji summarizing the content in the content's primary language.
### Guidelines:
- The title should clearly represent the main theme or subject of the content.
- Use emojis that enhance understanding of the topic, but avoid quotation marks or special formatting.
- Write the title in the content's primary language.
- Prioritize accuracy over excessive creativity; keep it clear and simple.
- Your entire response must consist solely of the JSON object, without any introductory or concluding text.
- The output must be a single, raw JSON object, without any markdown code fences or other encapsulating text.
- Ensure no conversational text, affirmations, or explanations precede or follow the raw JSON output, as this will cause direct parsing failure.
### Output:
JSON format: { "title": "your concise title here" }
### Examples:
- { "title": "📉 Stock Market Trends" },
- { "title": "🍪 Perfect Chocolate Chip Recipe" },
- { "title": "Evolution of Music Streaming" },
- { "title": "Remote Work Productivity Tips" },
- { "title": "Artificial Intelligence in Healthcare" },
