SMTP outbound as a first-class citizen: send emails without pip install yagmail

Notifications, password resets, magic links, alerts. Every language solves SMTP outbound with an external library. In Fitz, smtp.send(opts) is a language builtin. Async from day one. Bit-for-bit parity between fitz run and fitz build. No pip install yagmail / npm install nodemailer / cargo add lettre / Maven JavaMail.

The detail that gets forgotten

Any serious application eventually needs to send emails:

Notifications when a service goes down (incidents → on-call email).

Password reset / magic-link auth (unique link to the user's email).
