Tables with a download link stack on phones, the browser check covers the lookup, a hash typed in the search, breadcrumbs, previous and next across tabs, glossary terms and the 404 hint. validate_site budgets the Pagefind index pieces and takes the base path without mkdocs.yml. A test holds the picker to install.narrow() on 180 selections.

"""The file picker on Get your files lists what the installer installs.
|
|
|
|
The picker reads a compacted copy of each install/<platform>.json and keeps
|
|
a file when one of its systems is chosen, or when it has none and "other"
|
|
is chosen, then prints `--system` with the choices. install.py --system
|
|
narrows with install.narrow(). The two must agree file for file, or the
|
|
list the page shows is not what the command it prints installs.
