/**
 * Internal hook for translating Rebase UI strings.
 *
 * Uses the `rebase_core` i18next namespace that is initialised by
 * `RebaseI18nProvider`. Do NOT use `react-i18next` directly in internal
 * components — always go through this hook so the namespace is consistent.
 *
 * @example
 * const { t } = useTranslation();
 * <Button>{t("save")}</Button>
 *
 * @internal
