Implement light minimalistic tech redesign with Material 3
Complete transformation from dark to light theme with a professional, tech-forward design system featuring: - Material 3 theming with cyan-based color palette (#0891B2 primary) - Inter font family integration via Google Fonts - Comprehensive theme system (colors, spacing, typography, shadows) - Responsive component redesign across all screens - Enhanced UX with hover animations, Hero transitions, and shimmer loading - Accessibility features (reduced motion support, high contrast) - Clean architecture with zero hardcoded values Theme System: - Created app_colors.dart with semantic color constants - Created app_spacing.dart with 8px base spacing scale - Created app_theme.dart with complete Material 3 configuration - Added shimmer_loading.dart for image loading states UI Components Updated: - Book cards with hover effects and Hero animations - Bottom navigation with refined styling - All screens migrated to theme-based colors and typography - Forms and inputs using consistent design system Documentation: - Added REDESIGN_SUMMARY.md with complete implementation overview - Added IMPLEMENTATION_CHECKLIST.md with detailed task completion status All components now use centralized theme with no hardcoded values, ensuring consistency and easy future customization.
