1. Error Handling & Resilience
   Issue: Limited error handling, no retry logic for external API calls
   ∙ Nodes don’t handle API failures gracefully (nodes.py:80, 272)
   ∙ No retry mechanism for LLM calls, web scraping, or image generation
   ∙ Silent failures in image generation (nodes.py:275-276)
   Recommendations:

# Add exponential backoff retry decorator
from tenacity import retry, stop_after_attempt, wait_exponential

@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=2, max=10))
async def fetch_with_retry(url: str):
    ...

# Better error handling in nodes
try:
    image_url = await generate_image(image_prompt, image_provider)
except ImageGenerationError as e:
    self.log(f"Image generation failed: {e}", level="error")
    # Fallback to free image service
    image_url = await fetch_image_unsplash(fallback_query)
