"""
Smoke test: does Gemma 4 return usable bounding boxes for the
flood-risk indicators it identifies on a Street View image?

We don't assume any specific format. We ask explicitly for boxes,
dump the raw text response, and check what shape comes back:
  - Are the coords [y1,x1,y2,x2] (Gemini convention) or [x1,y1,x2,y2]?
  - Are they 0-1000 normalized, 0-1 normalized, or pixel coordinates?
  - Are they in a JSON field per indicator, or in a separate "boxes"
    array, or as natural-language descriptions?

Run:
    cd backend && set -a && source .env && set +a && \\
    PYTHONPATH=. .venv/bin/python scripts/smoke_test_bbox.py
