/**
 * Sidebar Layout Fix - Prevents overlapping and maintains footer visibility
 * 
 * This CSS addresses the issue where sidebar navigation items overlap 
 * with footer buttons (theme toggle, logout) when there are many menu items.
 * 
 * Solution approach:
 * 1. Create a proper flexbox layout for the sidebar
 * 2. Make the navigation area scrollable while keeping footer fixed
 * 3. Add proper spacing and visual separations
 * 4. Ensure responsive behavior on all screen sizes
