3. Video Master Adot Detection (BETA) - Intelligent 4-tier video matching system
4. Reporting - Consolidated reports from Box.com and internal QC modules

Key Features

• 🎯 Unified Interface - Single platform with tabbed navigation
• 🔒 Secure Authentication - Azure AD with JWT validation
• 🤖 AI-Powered - GPT-4o and Claude integration for intelligent validation
• 📊 Advanced Scoring - 0-100 confidence scoring with detailed breakdowns
• 🎨 H&M Branding - Consistent black (#000000) and yellow (#FFDD00) theme
• 🔄 Real-time Progress - SSE and polling support for long-running operations
• 📦 Modular Architecture - Flask blueprints for clean separation of concerns
