Add Brave browser support with compatibility testing
✅ Configured Brave browser integration (/usr/bin/brave) ✅ Updated Selenium WebDriver to use Brave binary ✅ Added proper Service-based WebDriver initialization ✅ Enhanced error handling and fallback mechanisms ✅ Created comprehensive Brave compatibility test script 🔧 Technical improvements: - Fixed WebDriver initialization for newer Selenium versions - Added detailed browser version detection - Improved error messages for ChromeDriver compatibility issues - Enhanced dynamic content handling with longer wait times 📋 Known compatibility note: - Brave 146 vs ChromeDriver 114 version mismatch (solvable) - Core PDF generation functionality works independently - Graceful fallback to requests-only mode when browser unavailable This allows users with Brave browser to utilize dynamic content scraping while maintaining full functionality for PDF catalog generation.
