+STEP 3 - train.py
+================
+
+Fine-tunes YOLOv8-nano on your augmented dataset.
+Pre-trained COCO weights give you a huve head-start - the backbone
+already knows edges, textures, and shapes; it only needs to learn
+what Famico (and other products) look like.
+
+Install:
+    pip install ultralytics
+
+Usage:
+    python train.py
+
+Outputs:
+    runs/detect/coffee_v1/weights/best.pt <- use this for detection
