-- `pixi run book` installs a user-wide ipykernel (`conda-env-se-for-sci-py`) and builds the site using `myst build --execute --html`. It sets `PYDEVD_DISABLE_FILE_VALIDATION=1`.

-- Only files listed in the `toc` section of `myst.yml` are included in the build. The `notes/` directory is explicitly excluded and contains instructor notes—do not reference it as book content.

 ## Content structure
 
 - `content/` — Book chapters (mix of `.md` and `.ipynb`).
-- `slides/` — Marp slide decks. These are rendered by CI and deployed to `public/slides`.

 ## Lint / format / pre-commit
 
 - Always use `prek -a --quiet` instead of `pre-commit run -a`.
-- Hooks include: ruff-format, blacken-docs, nbstripout, prettier, codespell, blocklint, plus a **custom `disallow-caps` hook** that rejects `PyBind`, `Numpy`, `Cmake`, `CCache`, `Github`, `PyTest`.
-- Prettier config (`.prettierrc.toml`): prose wraps at 80 chars by default, **but never for `slides/*.md`**.

 Linux is in Git. It's the basis of modern software development. We'll work on
 Git in detail later, but here are a few quick basics:
