name: Deploy website (fast)

# Fast path: builds and deploys ONLY the interactive website (no Lean build),
# so https://statlean.github.io/website/ goes live in minutes. The doc-gen4
# docs are pulled from the shared cache that the full `deploy.yml` workflow
# populates; if that cache is empty (docs not built yet) the website still
# deploys and /docs/ becomes available after the first full build.
