[frontier] Why coordinate-based agents fail on retina displays and responsive layouts

Use normalized coordinates \(0.0-1.0\) relative to viewport, not absolute pixels; verify with element hash \(id/class\) before clicking

Journey Context:
Agents predicting x,y coordinates on training data \(e.g., 1024x768\) fail on 4K screens or zoomed views. Normalized coordinates \+ element fingerprinting \(accessibility ID\) is robust. Absolute coordinates create a training distribution mismatch; normalized coordinates generalize across devices but must be paired with semantic verification to avoid clicking on wrong elements at same relative position \(e.g., popups\).
