+## Accessibility Attributes Summary
+
+### Data-TestID Attributes
+- **Total**: 131 components
+- **Pattern**: kebab-case, descriptive
+- **Examples**:
+ - `data-testid="colors-section"`
+ - `data-testid="dashboard-template"`
+ - `data-testid="top-app-bar-action"`
+
+### ARIA Attributes
+| Type | Count | Purpose |
+|------|-------|---------|
+| `aria-label` | 131 | Descriptive labels |
+| `role="region"` | 18 | Section landmarks |
+| `role="main"` | 4 | Template main content |
+| `role="banner"` | 1 | Top app bar header |
+| Additional roles | 15+ | Semantic structure |
+| `aria-hidden` | 67 | Decorative elements |
+| `aria-pressed` | 15 | Button states |
+| `aria-expanded` | 18 | Collapsible sections |
+| Other ARIA | 100+ | Various purposes |
+
+---
+
+## Testing Infrastructure
+
+### E2E Test Ready
+All components can now be reliably selected in tests:
+
+```typescript
+import { render, screen } from '@testing-library/react';
+
+// Button component
+const button = screen.getByTestId('top-app-bar-action');
+
+// Section component
+const section = screen.getByTestId('colors-section');
+
+// Template component
+const template = screen.getByTestId('dashboard-template');
+
+// Verify accessibility
+expect(section).toHaveAttribute('role', 'region');
+expect(section).toHaveAttribute('aria-label', 'Colors palette');
+```
+
+### Supported Testing Frameworks
+- ✅ Jest + React Testing Library
+- ✅ Cypress (element selection)

+## Lessons Learned
+
+### Successful Approaches
+1. **Consistent Patterns**: Using standard component patterns made implementation efficient
+2. **Naming Conventions**: Kebab-case testids are predictable and maintainable
+3. **Role Usage**: Proper semantic roles improve both accessibility and semantics
+4. **Documentation**: Comprehensive docs reduce future confusion
+
+### Best Practices Applied
+1. **Minimal Invasiveness**: Attributes added without functional changes
+2. **Descriptive Labels**: ARIA labels provide real context, not just placeholders
+3. **Semantic Structure**: Role attributes reflect component purpose
+4. **Testing Ready**: All selectors designed for E2E testing
