axi0 Tools (https://search.axi0.io/tools/): third-party code shipped with the page.

Everything on the page is our own code except the PDF engine below, which is fetched from this origin only when the
PDF tools get their first file. Nothing on the page talks to anyone else's servers; the API client sends only what
you compose, to the server you name.
