I inspected the existing navigation component, its state handling, Tailwind classes, and related responsive styles before changing anything. Implemented: Corrected the responsive overflow/layout behavior at narrow widths. Fixed the drawer close interaction without introducing a new state layer. Preserved the existing component architecture and styling conventions. Added appropriate focus behavior and keyboard-accessible interaction. Removed the conflicting utility classes responsible for the layout issue. Validation: Checked the affected component for React/state consistency. Verified the responsive class logic and interactive states. Confirmed no new dependency was required. I did not claim browser/runtime verification where the environment did not provide it.
