## 🚨 Critical Issues & Bugs
None detected.

## 💡 Suggestions & Best Practices

• login/index.html: The changes are excellent for screen reader compatibility. Just ensure that the CSS utility class sr-only is actually defined in your global stylesheet (e.g., Tailwind CSS provides this natively, but if this is a custom codebase, verify the class exists to prevent the heading from being visibly rendered).

## 📊 Final Assessment

• Rating: Good
• Reason: The modifications correctly implement standard accessibility practices without introducing any regressions, bugs, or security vulnerabilities. It is a clean and safe enhancement.
