+# Conventions:
+#   - The caller owns `set -euo pipefail` and PACKAGES_FILE.
+#   - Package lists use @pacman (default) / @aur / @npm section markers;
+#     '#' starts a comment, blank lines are ignored.
+#   - Set NPM_USE_SUDO=1 before calling install_npm_pkgs when the global
+#     npm root is root-owned (Arch installs npm to /usr/lib/node_modules).
+
+# Print the repository root (setup/lib/ -> repo root).
