Implement Solar Energy Portal with React, TypeScript, and Dual Theme System

[Copilot]

Created a complete React application for a solar energy and power tracking portal from scratch, implementing all specified requirements with modern web technologies and best practices.

Features Implemented

🎨 Dual Theme System

• Light Theme (Solar-inspired): Bright design with Solar Yellow (#FFD54F) and Eco Green (#66BB6A) accents on a clean white background
• Dark Theme (Blockchain-inspired): Modern dark interface with Solar Yellow (#FFEB3B) and Techy Teal (#26C6DA) accents on dark backgrounds
• Smooth transitions between themes with CSS custom properties
• Theme preference persisted in localStorage with system preference detection

📱 Responsive Design

• Mobile-first approach with breakpoints for all device sizes
• Components adapt gracefully from desktop to mobile
• Theme toggle button scales appropriately on smaller screens

⚡ Interactive Components

• Header: Solar Energy Portal branding with animated Orbitron font and glowing effects
• Theme Toggle: Animated button with sun/moon icons that smoothly switches between light and dark modes
• Scroll-to-Top: Appears after scrolling 300px with smooth animation and teal accent styling

🔧 Technical Implementation

• React 19 with full TypeScript support and proper type definitions
• Vite for fast development and optimized production builds
• CSS Custom Properties for maintainable theming system
• React Context for theme state management
• Google Fonts: Orbitron (headings), Inter (body), Exo 2 (accent) with fallbacks
• Clean, scalable file structure following React best practices

Architecture

The application follows a modular component architecture:

├── components/          # Reusable UI components
│   ├── Header/         # Portal branding with animations
│   ├── ThemeToggle/    # Theme switching functionality
│   └── ScrollToTop/    # Scroll-to-top button
├── contexts/           # React context providers
├── hooks/             # Custom React hooks
├── styles/            # Global CSS with theme variables
└── types/             # TypeScript type definitions
