Generate Enhanced Logo

async def generate_enhanced_logo(png_bytes: bytes) -> dict

{
    "success": True,
    "image_base64": "iVBORw0KGgo...",
    "image_data_url": "data:image/png;base64,iVBORw0KGgo..."
}

CRITICAL: You are receiving TWO images in a specific order:
- FIRST IMAGE (base_image.png): The Target retail company logo drawn in 
  hand-sketched style - this is ONLY for style reference
- SECOND IMAGE (target_image.png): A different company's favicon/logo - 
  this is what you MUST transform

YOUR TASK: Redraw the SECOND IMAGE using the hand-sketched artistic style 
from the FIRST IMAGE.
