Subject: [PATCH] Implement Dynamic Theme Switching (Dark/Light Mode)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit introduces a comprehensive theme system that allows users to seamlessly
switch between dark and light modes throughout the application.

🌟 Key Features:
• Toggle between dark and light themes with smooth transitions
• Automatic theme persistence using localStorage
• System preference detection for initial theme selection
• Comprehensive CSS variable system for consistent theming
• Theme-aware utility classes for easy component integration

🎨 What's Included:
• Theme Vuex store for state management and theme logic
• Complete CSS variable definitions for both light and dark modes
• Smooth 0.3s transitions for all theme-related properties
• Proper contrast ratios ensuring accessibility in both themes
• Support for all UI components including buttons, inputs, icons, and dropdowns

🚀 Developer Experience:
• Easy-to-use utility classes (.text-themed, .bg-primary, etc.)
• Centralized theme management through Vuex store
• Automatic document class updates (html.dark / html.light)
• No breaking changes to existing components

This enhancement significantly improves user experience by providing
visual comfort options and follows modern UI/UX best practices.
