// `archilyzer reports prepare <siteId>` — cut and copy the evidence media of a
// site's published reports into `.export-index/sites/<siteId>/report-media/`,
// before the site's build. The work is publish/reportMedia.ts's, the same the
// editor's `reports-prepare` job runs; this file prints its log and its
// problems.
//
// When nothing is missing it then exports the reports as files
// (publish/reportExports.ts, `archilyzer reports export`).
//
// Exit 0 when every cited moment has its media and every export was written;
// 1 when any problem is listed (the manifest is written either way, problems
// included); 2 for a site that does not exist.
