[frontier] Accessibility Tree Mirage: Agents rely on ARIA labels that differ from visible text \(e.g., aria-label='Submit' vs visual text='Buy Now'\)

Implement visual verification layer: use OCR to extract text from screenshot region and confirm semantic match with DOM element text before interaction. If ARIA differs from visual by >30% Levenshtein distance, trust the visual OCR and use Set-of-Mark coordinates instead of DOM selector.

Journey Context:
DOM-based agents \(Playwright get\_by\_role\) often target 'Submit' buttons that are visually labeled 'Complete Purchase' or 'Pay $50'. In React/Vue apps, developers use generic aria-labels for accessibility but custom styled visual text. Screenshot agents see the truth. The hybrid pattern is 'Visual Confirmation'—use the DOM to find interactive elements, but verify the text content via OCR before clicking. This prevents clicking the wrong button when multiple 'Submit' buttons exist with different visual labels.
