- Consolidated multi-line arguments into single lines where appropriate in `useAuth`.
- Improved spacing and readability in data processing across components (`ProfileSettingsForm`, `PasswordChangeForm`, `SessionCard`).
- Applied consistent table and markdown formatting in design system docs (e.g., `README.md`, `08-ai-guidelines.md`, `00-quick-start.md`).
- Updated code snippets to ensure adherence to Prettier rules and streamlined JSX structures.
- Introduced `__PLAYWRIGHT_TEST__` flag in `storage.ts` to bypass token encryption for improved E2E test stability.
- Rebuilt Profile Settings E2E tests to verify user data display with mock API responses.
- Refactored `setupAuthenticatedMocks` and `loginViaUI` to support new test requirements and streamline session setup.
- Removed outdated debug selectors test `test-selectors.spec.ts`.
- Introduced comprehensive tests for `RegisterForm`, `PasswordResetRequestForm`, and `PasswordResetConfirmForm` covering successful submissions, validation errors, and API error handling.
- Refactored forms to handle unexpected errors gracefully and improve test coverage for edge cases.
- Updated `crypto` and `storage` modules with robust error handling for storage issues and encryption key management.
- Removed unused `axios-mock-adapter` dependency for cleaner dependency management.
- Removed outdated `crypto` tests; added dedicated and structured tests for `authStore`, `storage`, and `app.config`.
- Enhanced test coverage for user and token validation, secure persistence, state management, and configuration parsing.
- Consolidated encryption and storage error handling with thorough validation to ensure SSR-safety and resilience.
- Improved runtime validations for tokens and configuration with stricter type checks and fallback mechanisms.
- Introduced SSR guards for browser APIs in `crypto` and `storage` modules.
- Enhanced resilience with improved error handling for encryption key management, token storage, and retrieval.
- Added validation for token structure and fallback mechanisms for corrupted data.
- Refactored localStorage handling with explicit availability checks for improved robustness.
- 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.
