Admins (with 2FA) can view the site as a non-admin user for up to 30
minutes, with a required reason and a "Viewing as" banner. It is
strictly read-only: a guard mounted before every route refuses any
write made with an impersonation token, protect/optionalAuth check the
session is live, and GET handlers skip the price-refresh writes. Start,
end, reason and every page/API call (including blocked attempts) are
audited; optional email to the user.
