1. // lib/mail.hl — THE MAILER. One hl:smtp Mailer, configured from `.env` beside project.hl
2. // (SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASSWORD, SMTP_FROM; the real environment
3. // outranks the file). A send is non-blocking: the SMTP conversation runs on the
4. // mailer's thread and its outcome arrives on the event loop (logged below).
5. //
6. // IDENT_MAIL_SINK names a file that receives the mail INSTEAD of the SMTP server: one
7. // line `<address> <code>` is APPENDED per code. The dev server and the gate use it, so
8. // no real mail is sent until SMTP is configured for mail.byrod.in (see README).
9. //
10. // Handlers belong to instances: project.hl constructs this file once (`mail = new Mail()`).
