[frontier] Screenshot-to-DOM reconciliation gaps causing agents to miss either visual affordances or semantic structure

Build hybrid perception layers using contrastive learning to dynamically map screenshot patches to DOM nodes, creating unified visual-DOM embeddings

Journey Context:
Pure DOM agents click invisible elements; pure vision agents miss ARIA labels. The fix is a 'Visual-DOM' alignment layer: use CLIP-style contrastive learning to map image patches to DOM node embeddings in a shared latent space. At inference, retrieve the nearest DOM node for any visual coordinate, getting both pixel precision and semantic accessibility data. This beats simple heuristics \(xpath from coords\) which break with responsive layouts.
