/**
 * i18next-cli workflow config for the whole monorepo.
 *
 * - `extract` pulls t()/<Trans> keys from the dashboard and CLI source into the
 *   authored `en` catalogs under @fusion/i18n.
 * - `sync` propagates the `en` key structure to the secondary locales.
 * - `types` regenerates key types from the `en` catalogs.
 * - `status` runs the project key-parity gate: structure only, empty values allowed.
 * - `status:report` preserves the upstream translation-completeness report.
 * - `lint` flags hardcoded user-facing strings (primary guardrail).
 *
 * FNXC:i18n-ParityGate 2026-06-20-00:00:
 * `pnpm i18n:status` points at packages/i18n/scripts/check-i18n-parity.mjs because empty secondary-locale values are intentional fallback placeholders, not gate failures.
 * Use `pnpm i18n:status:report` when a human wants the upstream completeness report that still counts empty placeholders as untranslated.
 *
 * Namespaces are routed by the `ns:` prefix in keys / `useTranslation(ns)` in
 * source, not by file path. `common` is the default namespace.
