Improve mobile responsiveness and touch target accessibility

[Copilot]

This PR addresses mobile user experience issues by implementing comprehensive touch target improvements, responsive layout optimizations, and network-friendly video handling.

Key Improvements

Enhanced Touch Target Accessibility

• Increased button minimum heights to 44px to meet WCAG AA accessibility guidelines
• Enhanced icon buttons to 44x44px with proper padding for comfortable mobile interaction
• Improved search input height from 36px to 44px for better touch accessibility
• Enlarged video player controls including play button and close button for mobile devices

Mobile Layout Optimizations

• Converted main CTA buttons from horizontal to vertical stack on mobile devices, providing better spacing and preventing accidental taps
• Enhanced responsive breakpoints to ensure smooth transitions across device sizes (320px to 768px+)
• Improved mobile navigation menu with better touch targets and hover states

Network & Performance Optimizations

• Optimized video loading strategy - video only loads when explicitly requested, reducing initial bandwidth usage on mobile networks
• Enhanced video accessibility with improved alt text and larger, more accessible controls
• Maintained production build performance with no impact on bundle size or loading times

Testing Results

Comprehensive testing across multiple mobile breakpoints:

• ✅ 320px (iPhone SE) - Excellent spacing and touch targets
• ✅ 375px (iPhone) - Optimal button layout and video interaction
• ✅ 414px (iPhone Plus) - Responsive layout scales well
• ✅ 430px (iPhone 14 Pro Max) - Adapts to larger mobile screens
• ✅ 768px (iPad) - Smooth transition to tablet layout

Before vs After

The improvements are clearly visible in the mobile layout transformation:

Before: Cramped horizontal button layout with insufficient touch targets

After: Spacious vertical button layout with proper touch targets

Technical Implementation

• Button Component: Enhanced size variants with mobile-first responsive approach
• Homepage Layout: Implemented responsive flex direction changes for button stacking
• Search Component: Increased input minimum height while maintaining desktop experience
• Video Component: Enhanced interaction areas for touch devices
• Navigation: Added mobile-optimized spacing and touch target compliance

All changes maintain backward compatibility and desktop experience while significantly improving mobile usability.

Fixes #254.
