""" Pixel-based hover detection for ChatGPT sidebar. Uses classical CV approach (no vision LLMs needed): 1. Capture sidebar screenshot 2. Divide into row bands 3. Measure background brightness deviation from normal (249) 4. Highlighted row has largest deviation (~239-246 vs 249) Achieves 100% accuracy on test images.
