#!/usr/bin/env node
// scripts/launch.mjs — cross-platform "prepare + start + open the browser", used by scripts/start-windows.bat,
// scripts/start-windows.ps1 and scripts/start.sh (docs/DEPLOY.md).
//
//   node scripts/launch.mjs [--port 3000] [--host 0.0.0.0] [--no-open] [--no-setup] [setup options…]
//
//   1. If our server already answers on the port, just open the browser (double-clicking twice is harmless).
//   2. node tools/setup.mjs --quiet (dependencies, vendor libs, art download / resume, optional local extraction);
//      setup options such as --no-assets, --no-local, --local, --game <dir>, -y are passed through.
//   3. node server/index.js (PORT / HOST from the options or the environment; SP_COMBAT / SP_VERIFY / TRUST_PROXY /
//      DEBUG are inherited), then — once /healthz answers — prints the addresses to share and opens
//      http://localhost:<port> (not with --no-open, SP_NO_BROWSER=1, or on a Linux box without a display).
// Ctrl+C stops the server (it gets the signal from the terminal itself); the exit code is the server's.
