-- Masonry feed с несколькими провайдерами и перемешанной выдачей All providers.
-- Поиск тегов через chip-input: ввел тег, нажал пробел или Enter, тег стал отдельным элементом.
-- Подсказки тегов из API активных провайдеров.
-- Избранное, коллекции и отдельная вкладка Viewed.
-- Smart blacklist/whitelist по тегам, группам тегов, рейтингу, провайдеру, типу файла и score.
-- Details viewer для фото, GIF, видео и SWF на Windows.
-- Видео-плеер с fullscreen, repeat, mute, half-volume и сохранением выбранных настроек.
-- Отдельная вкладка Artists для Kemono/Coomer: поиск авторов и просмотр их работ без смешивания с обычным booru feed.
-- Управление провайдерами, health-check и provider diagnostics.
-- Экспорт и импорт настроек JSON.
-- Автопроверка обновлений через Gitea Releases, скачивание и открытие APK/Windows installer прямо из приложения.

-- `lib/backend/providers` - API-провайдеры и ProviderManager.

-- `/post/:providerId/:postId` - details viewer.
-- `/favorites` - избранное.
-- `/viewed` - история просмотренных постов.

-- Gelbooru - `https://gelbooru.com`
-- Rule34 - `https://api.rule34.xxx`
-- Safebooru - `https://safebooru.org`
-- Konachan - `https://konachan.com`

-- Kemono - `https://kemono.su` (только Artists)
-- Coomer - `https://coomer.su` (только Artists, выключен по умолчанию)
-
-Realbooru оставлен в списке, но выключен по умолчанию, потому что его публичный API сейчас нестабилен.
-
-Поддерживаемые `apiType`: `gelbooru`, `rule34`, `realbooru`, `danbooru`, `moebooru`, `e621`, `kemono`, `coomer`.
-
-Один упавший провайдер не ломает общий feed: ошибка сохраняется в diagnostics, остальные источники продолжают отдавать посты.
-
-## Как добавить провайдера
-
-1. Добавить mapper в `lib/backend/mappers`, если формат ответа отличается.
-2. Реализовать `ContentProvider` или artist-only `ArtistProvider` в `lib/backend/providers`.
-3. Зарегистрировать новый `apiType` в `ProviderFactory`.
-4. Добавить config через Providers UI или seed в `ProviderRepository`.
-
-## Запуск и сборка
+## Запуск
 
 ```bash
 flutter pub get
-flutter analyze
-flutter test
 flutter run -d windows
-flutter build windows
-flutter build apk
+flutter run -d android
 ```
 
-Windows installer собирается через Inno Setup:
+## Сборка
 
 ```bash
-ISCC installer/Lunaris.iss
+flutter analyze
+flutter test
+flutter build apk
+flutter build windows
 ```
 
-## Безопасность
+Windows installer собирается через Inno Setup:
 
-- Feed работает с preview/sample metadata и не скачивает full files автоматически.
-- Скачивание фото/видео/SWF выполняется только по явному действию пользователя.
-- Приложение уважает rate limits и использует retry/backoff.
-- API keys/user data хранятся локально и попадают в export JSON только по действию пользователя.
+```powershell
+ISCC.exe installer\Lunaris.iss
+```
 
+## Как добавить провайдера
+
+1. Создать класс, реализующий `ContentProvider`.
+2. Добавить mapper к единой модели `Post`.
+3. Зарегистрировать `apiType` в `ProviderFactory`.
+4. Добавить seed config в `ProviderRepository`, если провайдер нужен по умолчанию.
+5. Добавить тесты parser/provider factory.
+
+## Безопасность
+
+- Feed работает только с metadata/preview, full file не скачивается автоматически.
+- Загрузка файлов происходит только по явному действию пользователя.
+- Приложение уважает API и rate limits сайтов.
+- NSFW/blur/blacklist настраиваются локально.
+- API keys/custom headers хранятся локально и экспортируются только через явный export settings.
