+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.

+# Genius: поиск метаданных и получение текста
+
+Реализован Go-провайдер `services/api/internal/genius` и отдельная команда
+`services/api/cmd/genius`. Поиск через API возвращает кандидатов, ссылки на изображения
+и исполнителя. Текст выбранной песни извлекается из HTML страницы: из контейнеров
+`data-lyrics-container` либо из `songPage.lyricsData.body.html` во встроенном состоянии.
+JavaScript не исполняется. Используется HTML-парсер `golang.org/x/net/html`.
+
+Это проверяемый первый этап: команда работает отдельно от сервера. Автоматическое
+дополнение каталога, хранение текстов в БД, аннотации и отображение в плеере пока
+не подключены. Поэтому переменная ниже пока нужна именно процессу команды,
+а не Docker Compose или веб-клиенту.
+
+## Почему Go
+
+Основной API Pipu написан на Go. Небольшой провайдер можно подключить к нему без
+отдельного Python-сервиса. LyricsGenius удобен для Python, но собственный адаптер
+позволяет явно контролировать выбор версии песни, сетевые ограничения и ошибки.
+HTML Genius не является стабильным API: при изменении разметки парсер потребует обновления.
+
+## Получение токена
+
+1. Войти или зарегистрироваться на https://genius.com.
+2. Открыть https://genius.com/api-clients и создать новый API Client.
+3. Указать название, например `Pipu Music`, и URL своего приложения. Если форма
+   требует Redirect URI, указать URL под своим контролем; для чтения с Client Access
+   Token OAuth-переходы и обработчик callback в Pipu не нужны.
+4. В созданном клиенте нажать **Generate Access Token**.
+5. Сохранить **Client Access Token** в переменной `GENIUS_ACCESS_TOKEN` процесса.
+   Client ID и Client Secret вместо него не подходят.
+
+Токен нужен для поиска через `api.genius.com`. Получение HTML по уже известному
+URL не требует токена и не отправляет заголовок Authorization. Не помещать токен
+в git, клиентские переменные `VITE_*`, логи или переписку.
+
+Источник: https://lyricsgenius.readthedocs.io/en/master/setup.html.
+
+## Проверка в PowerShell 7
+
+Из корня репозитория:
+
+```powershell
+Set-Location services/api
+$env:GENIUS_ACCESS_TOKEN = Read-Host 'Genius Client Access Token' -MaskInput
+go run ./cmd/genius -search 'Исполнитель Название песни'
+```
+
+Выбрать нужного исполнителя и версию песни из результатов. Команда намеренно
+не считает первый результат правильным. Затем подставить возвращённый `url`:
+
+```powershell
+go run ./cmd/genius -url 'https://genius.com/Artist-song-lyrics'
+Remove-Item Env:GENIUS_ACCESS_TOKEN
+```
+
+URL во втором примере — шаблон. Результат — JSON с `text`, `source_url` и временем
+получения `fetched_at`. Это обычный текст без временной синхронизации.
+
+## Ограничения и дальнейшее подключение
+
+- HTTP 401, 403, 404, 429 и другие ошибки возвращаются явно; `HTTPError` сохраняет
+  `Retry-After`. Автоматических повторов и обхода блокировок нет.
+- Таймаут запроса — 15 секунд, предел ответа — 8 MiB. Разрешён только HTTPS
+  на Genius; перенаправления на другой хост запрещены.
+- Отсутствие распознаваемого текста возвращает `ErrLyricsUnavailable`; HTML
+  блокировки или навигация не становятся текстом песни.
+- Перед интеграцией в каталог нужны кэш результатов, лимит частоты запросов,
+  сохранение выбранного Genius ID и обработка временных ошибок без потери старого текста.
+- Токен API не предоставляет лицензию на тексты. Документация LyricsGenius
+  предупреждает, что парсинг противоречит условиям Genius; отображление и хранение
+  в публичном сервисе требуют отдельной проверки разрешений:
+  https://lyricsgenius.readthedocs.io/en/latest/how_it_works.html.
+
+## Тесты
+
+```powershell
+go test ./internal/genius ./cmd/genius
+```
+
+Тесты используют синтетические тексты и подмену HTTP: переносы, HTML-сущности,
+служебные элементы, встроенное состояние, ошибки HTTP, проверка URL и
+отсутствие токена при запросе страницы. Реальный доступ к Genius проверяется
+отдельно из сети сервера с собственным токеном.

+# Личные плейлисты
+
+Плейлисты хранятся в PostgreSQL и доступны владельцу на вебе и в React Native-клиенте. В вебе раздел находится в коллекции; на узком экране — в меню «Ещё». В мобильном клиенте — кнопка «Плейлисты» в коллекции.
+
+Можно создать плейлист, изменить название и описание, добавить трек из поиска, альбома или коллекции, убрать трек и переместить его выше/ниже. В вебе можно добавить целый альбом. Один трек встречается в плейлисте один раз: повторное добавление не создаёт дубль. Воспроизведение доступно в сохранённом или случайном порядке; недоступные треки остаются видимыми, но пропускаются при запуске всего плейлиста. Удаление плейлиста требует подтверждения и не удаляет музыку из каталога.
+
+## API
+
+- `GET /api/v1/me/playlists` — сводки личных плейлистов, последние изменённые первыми.
+- `POST /api/v1/me/playlists` — создание: `name`, `description`, `track_ids`.
+- `GET /api/v1/me/playlists/{id}` — метаданные и упорядоченные треки с персональными реакциями и подписанными ссылками.
+- `PUT /api/v1/me/playlists/{id}` — атомарная замена метаданных и порядка треков; дополнительно требуется `revision` из прочитанного плейлиста.
+- `DELETE /api/v1/me/playlists/{id}` — удаление.
+
+Все операции требуют авторизации. Чужой и отсутствующий плейлист возвращают одинаковый `404`. Изменения блокируют строку плейлиста в транзакции; устаревшая версия возвращает `409 playlist.conflict`. Редактор сохраняет исходную версию до закрытия, даже если фоновый запрос получил новую. Ошибка трека откатывает изменение целиком. Ввод ограничен 120 символами названия, 2000 символами описания и 2000 уникальными треками.
+
+Миграция `00013_playlists.sql` создаёт таблицы `playlists`, `playlist_tracks` и индексы. Удаление пользователя очищает его плейлисты; удаление трека из каталога очищает его членство. Таблицы не затрагивают музыкальные файлы.
+
+Плейлисты личные; публичные ссылки, совместное редактирование и загрузка пользовательских обложек не входят в эту реализацию. Карточки имеют градиентную обложку, страница использует обложку первого трека. Контекст воспроизведения — `collection` с UUID и названием плейлиста.
+
+## Проверки
+
+- `pnpm --filter @pipu/web test src/App.test.tsx -t playlists`
+- `pnpm --filter @pipu/web test:e2e e2e/playlists.spec.ts`
+- `pnpm --filter @pipu/web build`
+- `pnpm --filter @pipu/mobile typecheck`
+- В `services/api`: `go test ./internal/playback ./internal/server`
+- С отдельной тестовой PostgreSQL/pgvector: `TEST_DATABASE_URL=… go test -tags integration ./internal/playback -run TestPlaylistPersistenceAndIsolation -v`. Проверяет сохранение порядка, изоляцию владельцев, откат при несуществующем треке, конфликт конкурентных записей и каскадное удаление членства.
