 /**
- * `Intl.supportedValuesOf('currency')` includes a handful of codes for currencies that have
- * actually been withdrawn/superseded since — unlike JVM/Android/Apple, there's no web API to
- * derive "currently assigned to some country" the way `java.util.Currency`/`NSLocale` do (see
- * [localeCurrencyCode] below), so this is a manually maintained exclusion list instead, checked
- * (2026-09-10) against the JVM's own live-derived set. Needs a new entry whenever another
- * currency is retired.
+ * Which currency codes `Intl.supportedValuesOf('currency')` returns is ICU-version-dependent, and
+ * some browsers' ICU data includes codes for currencies retired decades ago (AFA, ALK, AOK, AON,
+ * AOR, ...) alongside genuinely current ones — a moving target, and not one an exclusion list can
+ * keep up with. So rather than trying to exclude every historical code some browser might expose,
+ * this allowlists the ones actually still in use instead: unlike JVM/Android/Apple, there's no web
+ * API to derive "currently assigned to some country" the way `java.util.Currency`/`NSLocale` do
+ * (see [localeCurrencyCode] below), so this is a manually maintained list, taken directly from the
+ * JVM's own live-derived set (checked 2026-09-10). Needs a new entry whenever a currency changes.
