/**
 * Tetches Game Server — thin entrypoint.
 *
 * Everything game-related lives in `server/`.  This file only:
 *
 *   • loads environment variables,
 *   • bootstraps the world + sockets + Express app via `server/bootstrap.js`,
 *   • binds the HTTP server to the configured port.
 *
 * `npm run dev` and the deploy script both invoke this file.
