+Каждая фича, у которой есть строки для пользователя, также владеет своей
+`i18n/` подпапкой (`ru.ts`, `en.ts`) — одно пространство имён i18next на
+фичу (`auth`, `landing`, ...), русские словари как источник (`as const`),
+английские типизированы через `satisfies Translation<typeof ru>` из
+`shared/i18n/common.ru.ts`, так что расхождение ключей — ошибка компиляции.
+
 Правило раздела shared/feature: если код используется ровно в одной фиче —
 он живёт в этой фиче, а не в `shared/`. Переносить в `shared/` только когда
 появился второй потребитель — не заранее "на всякий случай" (YAGNI).
