[frontier] Accessibility-Rendering Duality Gap: DOM agents miss disabled states and visual affordances; Screenshot agents miss semantic structure

Maintain parallel DOM accessibility tree and screenshot streams with cross-modal validation—verify element state \(enabled/disabled\) exists in both representations before interaction

Journey Context:
Pure DOM agents click buttons that are visually disabled \(CSS opacity\) because the DOM disabled attribute isn't set. Pure screenshot agents miss semantic structure \(ARIA labels, hidden fields\). The emerging pattern is bimodal state machines: query the accessibility tree for structure, screenshot for visual confirmation, and reconcile discrepancies \(e.g., DOM says button exists but screenshot shows loading spinner = not clickable\). This catches CSS-generated content invisible to single-modality approaches.
