Plain-English load errors

Failures are shown as readable messages (password protected, not a valid PDF, not found, too large, host blocked the request, rate limited, permission denied) and most of them steer the author towards attaching the file to the page instead.

If nothing can be resolved at site build time the published page shows a plain note that the PDF could not be exported.
