/**
 * Bootstrap script for the distroless production image.
 *
 * Distroless images have no shell, so this Node.js script handles two tasks
 * that would normally be done in an entrypoint.sh:
 *
 * 1. Regenerate `public/__ENV.js` with the current runtime NEXT_PUBLIC_*
 *    environment variables.  The file was originally created at build time by
 *    next-runtime-env's `configureRuntimeEnv()`, but in a Docker deployment the
 *    env vars are provided at *run* time via docker-compose / docker run.
 *
 * 2. Start the Next.js standalone server.
