- Added `AuthContext` as a dependency injection wrapper over the Zustand auth store to support test isolation, E2E testability, and clean architecture patterns.
- Updated `layout.tsx` to utilize `AuthProvider` and initialize authentication context.
- Removed redundant `AuthInitializer` from `providers.tsx`.
- Enhanced modularity and testability by decoupling authentication context from direct store dependency.
- Implemented comprehensive tests for `useAuth` hooks (`useIsAuthenticated`, `useCurrentUser`, and `useIsAdmin`) with mock states and coverage for edge cases.
- Added tests for `AuthGuard` to validate route protection, admin access control, loading states, and use of fallback components.
- Updated `.gitignore` to exclude `coverage.json`.
- Centralized and refactored configuration management (`config`) with runtime validation for environment variables.
- Introduced utilities for secure token storage, including AES-GCM encryption and fallback handling.
- Enhanced `authStore` state management with token validation, secure persistence, and initialization from storage.
- Modularized authentication utilities and updated export structure for better maintainability.
- Improved error handling, input validation, and added detailed comments for enhanced clarity.
Implemented a full-stack template combining Next.js (frontend), FastAPI (backend), and PostgreSQL. Included Docker configurations for development and production, environment file templates, Makefile commands, and initial setup for database migrations and builds. The stack is production-ready and supports hot-reloading for local development.
