"""
Interactive runner for the YOLO object-detection inventory check.

Walks you through:
  1. Uploading the BASELINE (pickup) photo via a native file-picker dialog
  2. Uploading the RETURN photo the same way
  3. Detecting objects in both, with a running total per item type
  4. Comparing the two counts and reporting exactly what's missing

Run: python run_yolo_interactive.py
