Riverpod + go_router с auth-guard, NavigationRail на широком экране и bottom bar на узком. Токены в flutter_secure_storage, на web access живёт в памяти. Интерцептор подставляет токен и делает ровно один refresh на 401. Деньги приходят строками и форматируются через Decimal: парсить их в double значило бы терять копейки ровно там, где бэкенд их бережёт.
