+# Android App (Phase 0)
+
+Минимальный каркас Android-клиента на Kotlin + Jetpack Compose.
+
+## Что уже есть
+- Gradle multi-module root (`:app`)
+- Compose `MainActivity`
+- Базовые зависимости для дальнейшей реализации
+
+## Следующий шаг
+1. Добавить network layer (Retrofit/OkHttp + auth interceptor).
+2. Внедрить DI и feature-модули.
+3. Поднять auth flow (email-first) и chat list.
