Delivers MIL-003 (lecture Step 2): an alert e-mail with title, price and buy link is sent over SMTP (port 587, STARTTLS) when the price is below the target 100. SMTP address, e-mail address and password are read from `.env` with python-dotenv (`.env.example` lists them). Tests use fakes and never open a network or SMTP connection.
Review: code against QC-PY-001 as RC-012 (Go, autonomous, not independent). 33 pytest tests, ruff and mypy --strict pass. The Step 2 screenshots come from a run with a stubbed SMTP connection; no real mail was sent.
