+/**
+ * We use `export default puppeteer` in `src/index.ts` to expose the library But
+ * TypeScript in CJS mode compiles that to `exports.default = `. This means that
+ * our CJS Node users would have to use `require('puppeteer').default` which
+ * isn't very nice.
+ *
+ * So instead we expose this file as our entry point. This requires the compiled
+ * Puppeteer output and re-exports the `default` export via `module.exports.`
+ * This means that we can publish to CJS and ESM whilst maintaining the expected
+ * import behaviour for CJS and ESM users.
