      formats: ["es"], // pure ESM package
    },
    rollupOptions: {
      external: [
        ...Object.keys(pkg.dependencies), // don't bundle dependencies
        /^node:.*/, // don't bundle built-in Node.js modules (use protocol imports!)
      ],
    },
    target: "esnext", // transpile as little as possible
  },
