/**
 * 🎮 1v1 Interactive UDP Test
 * 
 * Tests real UDP/WebRTC interactivity between two browser instances.
 * Uses CDP to control both panes and inject simulated movement,
 * then verifies the other pane receives the UDP messages.
 * 
 * Implements a "camdoll" protocol for remote puppet control of pieces.
 * 
 * Usage: node artery/test-1v1-interactive.mjs [--duration <seconds>]

🎮 1v1 Interactive UDP Test

Tests real-time UDP/WebRTC interactivity by controlling two players
simultaneously in split view and verifying cross-communication.

Usage: node artery/test-1v1-interactive.mjs [options]

Options:
  --duration <seconds>   Test duration (default: 20, max: 60)
  --help, -h            Show this help

What it tests:
  • Opens split~1v1 (two 1v1 instances side by side)
  • Injects "camdoll" control bridge into both iframes
  • Simulates WASD movement on Player 1
  • Simulates strafing on Player 2
  • Verifies UDP messages flow between them
  • Reports message counts and connectivity status
