{#- The landing page used to draw a footer strip of its own to carry the version and the install route. That put a site-wide fact inside one page's body: it showed on the home page only, and every release had to remember to bump a line of prose in the middle of a Markdown file. Carry it here instead, beside the copyright, so every page states the version a reader would install and links to the artefact that ships it. The version comes from `extra.package_version` in `mkdocs.yml`, which a test pins to the version this tree packages. -#}
