Web Accessibility Heuristic Enhancer

A high-performance userscript that automatically improves accessibility on any website using advanced heuristics.
It enhances unlabeled buttons, links, forms, dialogs, regions, keyboard navigation, focus management, dynamic components, and infinite-scroll announcements — all without external APIs or dependencies.

✨ Features

• Smart ARIA role inference
• Advanced button + link labeling heuristics
• Repairs icon-only or visually unlabeled buttons
• Enhanced keyboard support (Enter, Space, Escape, Tab)
• Modal accessibility (focus trap, aria-modal)
• Dropdown & accordion accessibility
• Tab accessibility (roving tabindex + ARIA linking)
• Form accessibility (labels, errors, aria-required)
• Automatic region detection (header, nav, main, footer)
• Infinite scroll announcements (zero layout thrashing)
• Sticky header deduplication
• Fully reversible rollback system
• Memory-safe (GC for removed nodes)
• Hybrid MutationObserver scanning optimized for SPAs
