{{/* export_status — GET /d/{sqid}/export/{job}, where the button lands.

     Built twice (render.go): as a page, and as the bare "export-body"
     the shim polls. That is why the running and finished states are
     ALTERNATIVES rather than a result appended under a spinner — the
     shim keeps the first element of what it fetches and drops the
     rest, so a fragment has to be one element, and the element that
     replaces the spinner is the result.

     While it is running the element is ui's own job-status partial,
     which carries data-poll (and data-poll-push for a browser that can
     take server-sent events) and drops it when the job is done, which
     is what stops the loop. With scripts off the meta refresh below
     does the same job more slowly — and only while the job is running,
     or a finished page would refresh for ever. */}}
