# Task
Using https://docs.exa.ai, complete the following task:

Using Exa, build me a script that runs a small web research workflow:

1. Run TWO related searches:
   a. A broad query: "grid-scale battery storage advances"
   b. A more specific, recency-focused query: "grid-scale battery storage breakthroughs 2025"
2. Merge the results from both searches, deduplicate by URL, and select the top 5 most relevant results
3. If Exa supports fetching/extracting page content, retrieve the full content of the single most relevant result and write a 2-3 sentence summary grounded in that fetched content (not just the snippet)
4. Print the output as JSON with two keys:
   - "results": the top 5 deduplicated results, each with title, url, and snippet (or description)
   - "summary": your grounded 2-3 sentence summary of the top result (include the source url) 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
