Delivers MIL-002 (lecture Step 1): BeautifulSoup reads the title and the price (as a float, 99.99) from the practice page. Layers: domain (Product, errors), application (ports, read_product), infrastructure (scraper, HTTP client), main as composition root. Tests use a trimmed fixture of the practice page and never the network. Review: code against QC-PY-001 as RC-011 (Go, autonomous, not independent). 15 pytest tests, ruff and mypy --strict pass; a real run printed 99.99. Screenshots: docs/images/step-1-*.png.
