// VITE_PAYMENTS_DISABLED marks the thin native MVP that defers store billing (it hides the actions with
// no store pointer). Every other build (web, VK, Telegram, a billing-enabled RuStore native build) sells
// normally. purchasesHidden() folds both; isGooglePlayBuild() stays separate for the RuStore-pointer stub.
