Summary

Improve accessibility across interactive simulators, modals, and slide-out menus to achieve WCAG 2.1 AA compliance, with automated axe-core tests to prevent regressions.

Changes

Focus Management

  • NodeDetailPanel: Added useFocusTrap hook with Escape key listener so keyboard users can navigate and dismiss the slide-out panel
  • NotificationSidebar: Added useFocusTrap, Escape key listener, and aria-modal="true" for proper screen reader support

Automated Accessibility Testing

  • axe-core Playwright tests: New test suite (e2e/tests/accessibility.spec.ts) that injects axe-core and checks for critical/serious violations on:
    • Home page
    • Simulator page (with live ledger stream)
    • Notification sidebar (when open)
  • Keyboard navigation test: Verifies Tab key moves focus through interactive elements
  • Touch target test: Checks interactive elements meet 44×44px minimum touch target size (WCAG 2.5.8)

Acceptance Criteria

  • axe-core automated test runner reports 0 critical or serious accessibility violations
  • Screen readers announce ledger updates and simulation state changes (via existing aria-live regions + new focus traps)
  • Entire platform is navigable using keyboard-only navigation
  • Focus traps and Escape key listeners on all modals and slide-out menus

Closes #1146
