"""SocialSeed E2E Dashboard - Local Web Interface for Test Execution.

This module provides a visual interface to explore, run, and debug tests
without writing code constantly. It serves as the "Control Center" for the framework.

Features:
- Test Explorer: Visual tree view of all generated test modules
- One-Click Run: Execute individual tests, suites, or folders
- Rich Request/Response Viewer: Inspect headers, bodies, and status codes
- Parameterization: UI inputs to override test variables at runtime
- Live Logs: Real-time streaming of test execution logs
- Run History: View past test runs and their outcomes

Usage:
    e2e dashboard                    # Launch dashboard
    e2e dashboard --port 8501        # Launch on specific port
    e2e dashboard --open-browser     # Auto-open browser
