 - Guide landing layout: wrap the opening block in `docs/guide/index.md` with a `guide-intro-lead` container so the logo and first sections share one layout context for web and print.
 - `.gitignore` to exclude local build outputs `export/`, `site/`, and `_site_test/`.
 - `scripts/build_guide_pdf.py`: when the `CI` environment variable is set, pass Chromium flags (`--no-sandbox`, `--disable-setuid-sandbox`, `--disable-dev-shm-usage`) so headless print works on typical CI images.
