/**
 * The one OTP email template for every use of Auth\Services\OtpService —
 * not just admin login. A code confirming a destructive Artisan command
 * (e.g. Command\WipeCatalogCommand) reuses the exact same generation/
 * validation mechanism as login, but "Your login code" as the subject
 * would be actively misleading for that — the recipient never initiated a
 * login. $purpose is a small, fixed set of known keys (see
 * COPY_BY_PURPOSE), not free text — a typo'd/unknown purpose falls back
 * to 'login' rather than rendering a blank subject/intro.
