Commonly assumed
A developer might assume Puppeteer simply inherits the browsers-layer version value and prints the `@puppeteer/browsers` package version.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- Running `node_modules/puppeteer/lib/cjs/puppeteer/node/cli.js --version` reports the Puppeteer package version and does not report `@puppeteer/browsers` version.
- The Puppeteer CLI command exits successfully.
