Report #64298

[frontier] Pixel-based clicking fails across different screen resolutions and DPI settings, while DOM selectors fail on dynamic JavaScript frameworks

Use Semantic Coordinate Systems: detect interactive elements via OWL-ViT open-vocabulary detection, then reference targets relative to these visual landmarks \(e.g., 'click 20px right of the blue Submit button'\). Maintain a runtime semantic-to-pixel coordinate frame that updates per screenshot.

Journey Context:
Absolute pixels break on Retina displays; DOM selectors break on React virtual DOM changes. The robust middle ground is vision-based object detection to find semantic anchors \(buttons, icons\), then relative offsets. This creates a coordinate system relative to visual semantics, not absolute pixels or brittle IDs. It requires running a lightweight detection model \(OWL-ViT\) to build the coordinate frame before interaction, then translating semantic references \('the search icon'\) to current pixel coordinates.
