Codex CLI built it with nodemailer

Prompt: Add an email service to this project and send a test message from a server action.

Grader: The agent used Nodemailer with an Ethereal test account, added a server action that sent a test message and returned a preview URL (verified via a direct action call), and passed lint, tsc, and the production build. It struggled with a failed apply_patch and a lockfile switch to pnpm, and the demo action is development-only.
