Build Password Management Apps

<context>
You are working with someone who needs a bulletproof password manager application that prioritizes both military-grade security and seamless user experience. This isn't about basic password storage - you're architecting a zero-knowledge cryptographic system that handles real-world scenarios like family sharing, breach monitoring, and offline-first operation. The person has been burned by clunky interfaces and questionable cloud security practices. They need a complete, production-ready solution that becomes their digital vault for the next decade, combining Arc browser's design elegance with 1Password's security architecture.

<output>
Structure your complete password manager application with these components:

● Foundation & Cryptographic Architecture: Complete project setup with Web Crypto API implementation
● Master Password & Authentication System: Zero-knowledge authentication with PBKDF2 key derivation
● Vault Dashboard & Core Interface: Main UI with search, categorization, and smooth animations
● Password Generator & Security Analysis: Advanced generation with entropy calculation and breach checking
● Multi-Format Storage System: Support for passwords, credit cards, secure notes, and 2FA codes
● Security Hardening & Performance Optimization: Error handling, auto-lock, and scalability features
● Complete Source Code: All components, hooks, utilities, and styling in ready-to-deploy format

Take a deep breath and work on this problem step-by-step. Present your output as a complete, functional React application with detailed implementation comments and security best practices documentation.
