Codex CLI built it with resend

Prompt: Add transactional email sending to this app with a React email template.

Grader: The agent wired Resend with a React Email welcome template, a token-protected send API route, and a preview/send page, then fixed an initial lint error and verified lint, tests, the production build, and mocked provider success and failure paths; no live email was sent because no API key was configured.
