BROWSER COMPATIBILITY IMPROVEMENTS

To ensure the website works well across all browsers, the following changes have been made:

1. Added X-UA-Compatible meta tag to all HTML files
   - This ensures Internet Explorer uses the latest rendering engine

2. Enhanced viewport meta tag
   - Added maximum-scale=5.0 for better accessibility

3. Added multiple favicon formats for cross-browser compatibility:
   - SVG favicon (modern browsers)
   - ICO favicon (older browsers)
   - Apple Touch Icon (iOS devices)

   Note: You need to create these files from your FAVICON.svg:
   - favicon.ico (16x16, 32x32, 48x48 sizes)
   - apple-touch-icon.png (180x180 size)

4. Added polyfill.io script to all pages
   - This automatically provides JS polyfills only to browsers that need them
   - Supports older browsers like IE11 and older versions of Safari

5. Ensured all HTML files have consistent head structure
   - Same meta tags
   - Same ordering of elements
   - Same cross-browser compatibility features

These changes ensure the website will work properly across:
- Chrome, Firefox, Safari, Edge (modern versions)
- Internet Explorer 11
- iOS Safari and Android browsers
- Older browser versions with polyfill support
