Use Pixi from the repository root (recommended):

1. Install one environment (first time only): pixi install -e test-cu13 (or test-cu12).
2. Ensure the version is included in docs/nv-versions.json (and docs/versions.json if needed).
3. Build the docs with pixi run -e test-cu13 build-docs.
4. The HTML artifacts will be under both docs/build/html/latest and docs/build/html/<version>.

Build only the latest version with:

pixi run -e test-cu13 build-docs latest-only

If you are already in a prepared shell environment, you can still run ./build_docs.sh (or ./build_docs.sh latest-only) from docs/.

To publish docs, keep older docs/build/html/<version> directories intact for the version switcher.
