{#- The footer (WP-2021): the landing page's line, item for item, so the site ends the same way on every page (`docs/landing/src/shell.html`), then the release this tree documents. It replaces pydata's credits for Sphinx and for the theme. `data-docs-version` is the version this build is (`sphinx_shared.DOCS_VERSION`). The stylesheet reads it to tell a development tree's banner from an old release's (`custom.css` ยง The version banner). -#}
