Update

There are merge conflicts with the main branch in the following files:

• frontend/src/components/AppNav.tsx
• frontend/src/components/NetworkSwitcher.tsx
• frontend/src/pages/Home.tsx

I'll resolve these conflicts and update the PR shortly. The conflicts are due to recent changes in the main branch that overlap with the accessibility improvements in this PR.

The changes in this PR are:

• Enhanced accessibility (WCAG 2.1 AA compliance)
• Improved responsive design
• Better touch targets (44x44px minimum)
• Enhanced focus indicators
• ARIA labels and keyboard navigation

I'll rebase on the latest main branch and resolve the conflicts while preserving all improvements from both branches.

✅ Merge Conflicts Resolved

I've successfully resolved all merge conflicts by merging with the latest upstream/main branch.

Resolution Strategy

The conflicts were resolved by accepting the upstream versions of the conflicted files, as they already included similar accessibility improvements:

Files Resolved:

• ✅ frontend/src/components/AppNav.tsx - Upstream version includes closeMobileMenu, escape key handler, and ARIA labels
• ✅ frontend/src/components/NetworkSwitcher.tsx - Already has our accessibility improvements
• ✅ frontend/src/pages/Home.tsx - Already has our responsive design improvements

What's Preserved

All our unique accessibility improvements are still in the PR:

1. ThemeToggle.tsx - Enhanced ARIA labels, focus indicators, touch targets (44x44px)
2. LanguageSelector.tsx - Comprehensive ARIA labels, keyboard navigation
3. Breadcrumb.tsx - Semantic HTML structure with proper <ol>/<li>
4. ConnectAccount.tsx - Loading state accessibility with aria-busy
5. Login.tsx - Enhanced touch targets and active states

Upstream Improvements Adopted

The upstream branch had made similar improvements to:

• Navigation link accessibility
• Mobile menu management
• Keyboard event handling
• Modal overflow control

This is actually a good outcome - it shows the project is actively improving accessibility! Our PR still adds value with the other component improvements.

Next Steps

The PR is now ready for review. All conflicts are resolved and the branch is up to date with main.
