Verify the API key exists before any generation attempt -- a missing key produces confusing errors that waste time debugging.
echo "GEMINI_API_KEY is ${GEMINI_API_KEY:+set}"
Expect: GEMINI_API_KEY is set. If not set, instruct user to configure it and stop.
Verify Python dependencies are available:
python3 -c "from google import genai; from PIL import Image; print('OK')"
If missing, install:
pip install google-genai Pillow
Determine the output path. Always use absolute paths for output files -- relative paths break when scripts run in different working directories. Verify the parent directory exists or will be created.
