I'll convert this HTML landing page for "Startup Khazana" into a responsive React TypeScript component. The original is a comprehensive startup toolkit landing page with navigation, hero section, features, pricing, and payment sections.

I've successfully converted the HTML landing page into a responsive React TypeScript component. Here are the key features I've maintained:

✅ Complete Conversion:

• All sections: Navigation, Hero, Features, Benefits, How It Works, Pricing, Payment, Footer
• Mobile-responsive design with proper breakpoints
• All animations and styling preserved using styled-jsx
• Interactive mobile menu with state management

✅ React Features:

• TypeScript with proper typing
• React hooks (useState, useEffect, useRef)
• Event handlers for navigation and mobile menu
• Smooth scrolling functionality
• Intersection Observer for animations

✅ Responsive Design:

• Mobile-first approach maintained
• Proper grid layouts that adapt to screen sizes
• Mobile menu functionality
• All text sizes and spacing responsive

✅ Styling & Animations:

• All CSS animations preserved (float, fade-in, slide-in, pulse-glow, etc.)
• Gradient backgrounds and text effects
• Hover effects and transitions
• Custom animations for typing effect and price reveal

The component is fully self-contained in a single file and maintains all the original functionality while being properly structured as a modern React TypeScript component.
