/**
 * Automaker - Production Mode Launch Script
 *
 * This script runs the application in production mode (no Vite dev server).
 * It builds everything if needed, then serves static files via vite preview.
 *
 * Key differences from dev.mjs:
 * - Uses pre-built static files instead of Vite dev server (faster startup)
 * - No HMR or hot reloading
 * - Server runs from compiled dist/ directory
 * - Uses "vite preview" to serve static UI files
 *
 * Usage: npm run start
