Review corrections and additions (October 2026)

These changes are part of the current edition.

• If a link does not open, an offline route shows where every download lives in the course source.
• Setup: one clearly named notebook kernel for each environment, step-by-step notebook setup, and a WSL route for the framework modules on Windows.
• Practice: clearer instructions and feedback that names the call that failed. Modules 1–4, 7 and 9–14 gain a reasoning task and an exercise on the complete study's real results, matching the real-data sandboxes Modules 5, 6 and 8 already had.
• Concepts: each concepts page ends with three "Check yourself" questions.
• New exercises: stability and tuning (with gradient boosting) in Module 6, categorical encoding in Module 3, evaluated retrieval in Module 10, a JSON API in Module 12, and optional experiment tracking.
• Finding your way: a learner-first site menu, learning paths, and maintainer material moved out of search.

Learning outcomes are unchanged.
