+# Десктоп (`apps/desktop`)
+
+Windows, Linux и macOS: тот же веб-клиент в окне [Tauri 2](https://tauri.app/). Запросы к API идут через локальный прокси на `127.0.0.1`, чтобы плеер не открывал чужой origin. Refresh-токен хранится в системной связке ключей. Тип клиента — `desktop`.
+
+При первом запуске нужно указать адрес сервера (как в Android). Дальше вход тот же, что в вебе. Кнопка «Другой сервер» в настройках забывает адрес и токен. Трея: левый клик открывает окно; меню — открыть и выход. Клавиши медиаплеера ОС управляют воспроизведением.
+
+Плейлисты, ссылка на трек и остальной интерфейс совпадают с вебом. Сборка подставляет версию из git-тега.
+
+```bash
+pnpm --filter @pipu/desktop icons
+pnpm --filter @pipu/desktop dev
+pnpm --filter @pipu/desktop bundle
+```
+
+На Windows получается NSIS-установщик, на Linux — AppImage, deb и rpm. Зависимости Linux: WebKitGTK 4.1, AppIndicator, libsecret, GStreamer.
