// `archilyzer reports export <siteId> [--report <id>] [--formats html,pdf,md,slides,slides-pdf,zip]`
// — write a site's published reports as files (report.html, report.pdf,
// report.md, slides.html, slides.pdf, evidence-pack.zip) into
// `.export-index/sites/<siteId>/report-exports/<reportId>/`, where compose
// publishes them from. The work is publish/reportExports.ts's, the same the
// editor's `reports-export` job runs; this file prints its log and problems.
//
// Exit 0 when every asked-for export was written (a PDF skipped for want of a
// browser is a note, not a problem); 1 when any problem is listed; 2 for bad
// arguments or a site or report that does not exist.
