Currency was free text in the tariff editor (composer page + lab draft
modal — shared form) and the subscription plan editor; a typo could
publish an unknown code onto immutable versions. Both now offer a closed
select from lib/currencies.ts. An out-of-set code already stored on an
old record is appended as an extra option so it displays + round-trips
unchanged. Blank tariff form defaults to ALL (was EUR) — the site's
actual currency.
