  // `*.ts` helper scripts are run with ts-node, which executes them as CommonJS. The base config's
  // `module: esnext` / `moduleResolution: bundler` is an ESM-only combo that makes ts-node hand the
  // `.ts` file to Node's native ESM loader (which can't load `.ts`). ts-node merges this `ts-node`
  // key across the `extends` chain, so this single override covers every package that extends this config.
