// `emit` is what rp-setup-discovery runs after it writes the setup plan and requirements (before it stamps
// the plan): it adds the `import-site-locale` requirement and step as a pair, after notification safety,
// even when the source file is missing so setup fails closed instead of exempting the migration.
// `preview` is what rp-execution-policy runs while it builds the execution plan: it prints the plain-language
// section ("set currency / time zone / language to ...") from the source file alone. It reads no site.
// `status` prints whether the step is planned and whether the owner's question is open.
//
// The step itself runs in `rp-execute-setup`; this script never writes to the site.
//
// Exit codes: 0 done (including "nothing to do"); 3 the owner's question is open; 4 blocked (unusable source
