+- Target for all content
+
+### Level AA (Standard)
+- Comprehensive accessibility
+- Required by most regulations

+
+## Trade-offs to Consider
+
+| Decision | Benefit | Cost |
+|----------|---------|------|
+| Stricter compliance | Better access for more users | More development effort |
+| Automated-only testing | Faster audit | Misses ~70% of issues |
+| Manual testing | Comprehensive results | Time-intensive |
+| Progressive remediation | Prioritized fixes | May leave some users behind |
