 Remnawave Minishop - Telegram-бот и Web App (Mini App) для продажи и управления подписками Remnawave. Бот обрабатывает регистрацию, оплату, продление, пробный период, промокоды, рефералов и поддержку в чате. Web App показывает ссылку подключения, срок действия, трафик, оплату, устройства и вход по Telegram Mini Apps `initData`, Telegram OAuth / OpenID Connect и одноразовому email-коду.

Кнопка предпросмотра открывает `/home?theme_preview=<key>` и не меняет глобальную тему до сохранения.

+# Темы и внешний вид Web App
+
+Web App поддерживает файловые темы, предпросмотр и базовую настройку внешнего вида из админ-панели. Тема может быть простой цветовой схемой на JSON-токенах или полноценным скином с собственным CSS, шрифтами, иконками и графикой.
+
+## Что можно поменять
+
+Через раздел **Админка -> Внешний вид** можно:
+
+- выбрать глобальную тему Web App;
+- изменить accent-цвет конкретной темы;
+- включить или выключить применение темы в админ-панели;
+- настроить масштаб логотипа на главной и экране входа;
+- загрузить логотип файлом или по HTTPS-ссылке;
+- включить emoji-логотип и выбрать способ его отрисовки;
+- открыть предпросмотр темы через `/home?theme_preview=<key>`.
+
+Через файлы темы можно менять намного больше:
+
+- базовые цвета Mini App и админки;
+- радиусы, семейства шрифтов и размер главного логотипа;
+- любые компоненты через CSS: карточки, навигацию, таблицы, модалки, кнопки, скелетоны, прогресс-бары, состояния hover/active и мобильную/desktop-верстку;
+- иконки и изображения, если CSS ссылается на ассеты темы;
+- стили только пользовательской части, только админки или обеих частей сразу.
+
+Готовые темы лежат в `bot/app/web/themes`: `dark`, `light`, `windows95`, `ascii`. При первом запуске они копируются в `WEBAPP_THEMES_DIR`, по умолчанию `data/themes`.
+
+## Где живут темы
+
+Каждая тема - отдельная папка:
+
+```text
+data/themes/
+  neon/
+    theme.json
+    style.css
+    icons/
+      save.png
+```
+
+Путь настраивается переменной:
+
+```env
+WEBAPP_THEMES_DIR=data/themes
+WEBAPP_DEFAULT_THEME=
+```
+
+`WEBAPP_DEFAULT_THEME` опционален. Если он задан и совпадает с ключом темы, он переопределяет `default: true` в `theme.json`. Если переменная пустая, дефолт выбирается из дескрипторов тем.
+
+Важно: `WEBAPP_PRIMARY_COLOR`, `WEBAPP_LOGO_URL`, `WEBAPP_LOGO_USE_EMOJI`, `WEBAPP_LOGO_EMOJI` и `WEBAPP_LOGO_EMOJI_FONT` больше не являются рабочим способом первичной настройки через `.env`. Эти значения редактируются в админке и сохраняются как overrides в базе. Тема при этом может использовать сохраненный primary color как fallback accent.
+
+## Контракт `theme.json`
+
+Минимальная тема:
+
+```json
+{
+  "key": "neon",
+  "names": {
+    "ru": "Неон",
+    "en": "Neon"
+  },

+
+Поля верхнего уровня:
+
+| Поле | Назначение |
+| --- | --- |
+| `key` | Уникальный ключ темы, 1-64 символа: латиница, цифры, `_` и `-`. Если ключ не указан, берется имя папки. |
+| `names` | Локализованные названия, например `ru` и `en`. |
+| `enabled` | Показывать тему пользователям. Отключенная тема не попадает в публичный каталог. |
+| `default` | Делает тему выбранной по умолчанию, если `WEBAPP_DEFAULT_THEME` не задан. |
+| `use_primary_accent` | Если `true`, тема может получить accent из настройки внешнего вида, когда в `tokens.accent` ничего нет. |
+| `use_in_admin` | Если `false`, пользовательская часть использует тему, но админка откатывается на `dark`. |
+| `css_file` | CSS-файл внутри папки темы. Может быть `style.css` или вложенный путь вроде `css/theme.css`. |
+| `assets_version` | Версия ассетов. Для встроенных тем используется для обновления старых файлов в `data/themes`. |
+| `tokens` | Дизайн-токены, которые превращаются в CSS-переменные на `.app-shell`. |
+
+## Токены
+
+Поддерживаемые токены:
+
+| Токен | CSS-переменная | Что меняет |
+| --- | --- | --- |
+| `color_scheme` | `color-scheme` | Нативная светлая/темная схема браузера: `dark` или `light`. |
+| `style_preset` | CSS-класс пресета | Сейчас `win95`/`windows95` добавляет `theme-preset-win95`; остальные значения не дают специального класса. |
+| `accent` | `--accent` | Главный акцент: активные элементы, кнопки, прогресс, фокус. Только hex `#RGB` или `#RRGGBB`. |
+| `bg` | `--bg` | Основной фон приложения. |
+| `panel` | `--panel` | Основные карточки и поверхности. |
+| `panel_2` | `--panel-2` | Вторичные поверхности. |
+| `panel_3` | `--panel-3` | Поверхности повышенной вложенности, dropdown/popover. |
+| `border` | `--border` | Обычные границы. |
+| `border_strong` | `--border-strong` | Усиленные границы и hover-состояния. |
+| `text` | `--text` | Основной текст. |
+| `muted` | `--muted` | Вторичный текст. |
+| `dim` | `--dim` | Еще более тихий текст и служебные подписи. |
+| `danger` | `--danger` | Ошибки и опасные действия. |
+| `blue` | `--blue` | Синий вспомогательный цвет. |
+| `radius` | `--radius` | Базовый радиус карточек, кнопок и контролов. |
+| `font_sans` | `--font-sans` | Основной шрифт интерфейса. |
+| `font_logo` | `--font-logo` | Шрифт бренда и заголовка. |
+| `font_mono` | `--font-mono` | Моноширинный шрифт. |
+| `home_logo_scale` | `--home-logo-scale` | Масштаб логотипа на главной и входе, от `50` до `300` процентов. |
+| `admin_bg` | `--admin-bg` | Фон админ-панели. |
+| `admin_surface` | `--admin-surface` | Основные карточки админки. |
+| `admin_surface_2` | `--admin-surface-2` | Вторичные поверхности админки. |
+| `admin_elev` | `--admin-elev` | Elevated-поверхности админки. |
+| `admin_border` | `--admin-border` | Границы админки. |
+| `admin_border_strong` | `--admin-border-strong` | Усиленные границы админки. |
+| `admin_text` | `--admin-text` | Основной текст админки. |
+| `admin_muted` | `--admin-muted` | Вторичный текст админки. |
+| `admin_dim` | `--admin-dim` | Тихие подписи админки. |
+
+Если `css_file` не задан, интерфейс полностью строится на токенах и общих стилях. Если `css_file` задан, токены все равно применяются первыми, а CSS темы может уточнить или полностью переопределить внешний вид.
+
+## CSS-слой темы
+
+CSS темы подключается как:
+
+```text
+/webapp-theme-css/<key>/<css_file>
+```
+
+Например `data/themes/neon/style.css` будет доступен как `/webapp-theme-css/neon/style.css`.
+
+Корневой контейнер получает классы:
+
+```text
+app-shell theme-dark theme-key-neon theme-css-style
+```
+
+Для светлой схемы будет `theme-light`. Класс `theme-key-<key>` - основной якорь для CSS темы. Всегда начинайте селекторы с него, чтобы тема не задевала другие режимы:
+
+```css
+.theme-key-neon.app-shell {
+  --surface-sheen: rgba(168, 85, 247, 0.12);
+  --shadow-soft: 0 18px 48px rgba(12, 5, 30, 0.44);
+}

+Ограничения:
+
+- CSS-файл должен быть внутри папки темы;
+- размер CSS - до 512 KiB;
+- путь не может содержать `..`;
+- удаленные CSS, `data:` и protocol-relative URL в `css_file` не подключаются.
+
+## Ассеты темы
+
+Картинки темы кладутся рядом с `theme.json` и отдаются через:
+
+```text
+/webapp-theme-assets/<key>/<path>
+```
+
+Пример:
+
+```css
+.theme-key-neon .btn-primary::before {
+  content: "";
+  width: 16px;
+  height: 16px;
+  background: url("/webapp-theme-assets/neon/icons/spark.png") center / contain no-repeat;
+}
+```
+
+Разрешены `png`, `jpg`, `jpeg`, `gif`, `webp`, `svg`, `ico`. Один asset - до 1 MiB. Для шрифтов лучше использовать внешние источники, уже разрешенные CSP (`fonts.googleapis.com`, `fonts.gstatic.com`, `cdn.jsdelivr.net`) или системные fallback-цепочки в `font_*` токенах.
+
+## Пайплайн создания новой темы
+
+1. Выберите ключ темы.
+
+   Ключ должен быть стабильным: по нему сохраняется выбранная тема и строятся URL ассетов. Используйте короткий slug: `neon`, `brand_dark`, `terminal-blue`. Не переименовывайте ключ после публикации без миграции файлов и сохраненных настроек.
+
+2. Создайте папку в `WEBAPP_THEMES_DIR`.
+
+   В Docker по умолчанию это `data/themes`. Если включен bind mount `./data:/app/data`, убедитесь, что контейнер может писать в `data`.
+
+   ```bash
+   mkdir -p data/themes/neon
+   ```
+
+3. Скопируйте ближайшую базовую тему.
+
+   Для обычной брендовой темы чаще всего удобнее начать с `dark` или `light`. Для глубокого CSS-скина можно взять `ascii` или `windows95` как пример того, насколько далеко можно уйти от стандартного вида.
+
+   ```bash
+   cp bot/app/web/themes/dark/theme.json data/themes/neon/theme.json
+   ```
+
+4. Отредактируйте `theme.json`.
+
+   Сначала поменяйте `key`, `names`, `default`, `use_primary_accent` и базовые токены. На этом этапе можно вообще не создавать CSS: приложение уже увидит тему как новый набор токенов.
+
+5. Запустите приложение и откройте админку.
+
+   Раздел **Внешний вид** загружает `/api/admin/themes`, backend читает `WEBAPP_THEMES_DIR`, добавляет обязательные базовые темы и возвращает каталог. Нажмите **Обновить**, если папка была создана во время работы приложения.
+
+6. Проверьте тему через предпросмотр.
+
+   В карточке темы нажмите **Предпросмотр** или откройте:
+
+   ```text
+   https://app.domain.com/home?theme_preview=neon
+   ```
+
+   Предпросмотр не меняет глобальную тему и удобен для проверки CSS до публикации.
+
+7. Подберите accent и масштаб логотипа.
+
+   В админке можно менять accent и `home_logo_scale` без ручного редактирования JSON. При сохранении backend перепишет `theme.json` в `WEBAPP_THEMES_DIR`, выставит ровно один `default` и сбросит кеш публичных настроек.
+
+8. Добавьте `style.css`, если токенов мало.
+
+   Создайте файл, укажите его в `theme.json`:
+
+   ```json
+   {
+     "css_file": "style.css"
+   }
+   ```
+
+   Начинайте с переопределения CSS-переменных на `.theme-key-neon.app-shell`, затем переходите к конкретным компонентам. Проверяйте минимум: главная, оплата, настройки, модалки, админский дашборд, таблица пользователей, редактор тарифов.
+
+9. Добавьте ассеты при необходимости.
+
+   Положите картинки в подпапку темы и ссылайтесь на них через `/webapp-theme-assets/<key>/...`. Не используйте относительные пути вроде `url("icons/x.png")`, если CSS может быть подключен с другого URL-уровня; явный `/webapp-theme-assets/neon/icons/x.png` надежнее.
+
+10. Настройте поведение админки.
+
+    Если тема сильно декоративная и мешает рабочей админке, выставьте `use_in_admin: false`. Пользователи увидят тему, а администраторы в разделе админки получат `dark` как fallback.
+
+11. Сделайте тему дефолтной.
+
+    Есть два способа:
+
+    - в админке выбрать тему и сохранить;
+    - указать `WEBAPP_DEFAULT_THEME=neon` в `.env`, если нужен жесткий override на уровне окружения.
+
+12. Зафиксируйте тему.
+
+    Для темы, которая должна ехать вместе с проектом, добавьте ее в репозиторий в `bot/app/web/themes` и при необходимости расширьте `DEFAULT_THEME_KEYS` в `config/webapp_themes_config.py`. Для приватной инсталляции достаточно хранить ее в `data/themes`.
+
+## Насколько глубоко можно менять вид
+
+Уровни кастомизации:
+
+1. **Быстрый бренд** - токены `accent`, `bg`, `panel`, `text`, `radius`, логотип в админке. Код не нужен.
+2. **Полная палитра** - все пользовательские и admin-токены, отдельные шрифты, масштаб логотипа.
+3. **CSS-скин** - переопределение карточек, навигации, таблиц, модалок, progress/skeleton/toast, desktop/mobile раскладок.
+4. **Почти новый UI** - тема вроде `windows95` или `ascii`: можно менять форму контролов, иконки, эффекты, таблицы и визуальный язык целиком, пока сохраняется DOM и интерактивные состояния.
+
+Не стоит менять через CSS смысловые состояния: скрывать ошибки, отключать фокус, перекрывать кнопки невидимыми слоями или делать `display: none` для обязательных действий оплаты и авторизации. Тема должна менять внешний вид, а не бизнес-логику.
+
+## Диагностика
+
+Если тема не появилась:
+
+- проверьте, что `theme.json` лежит ровно в `WEBAPP_THEMES_DIR/<key>/theme.json`;
+- ключ состоит только из латиницы, цифр, `_` и `-`;
+- JSON валиден;
+- тема не отключена через `enabled: false`;
+- в логах нет предупреждения `Ignoring theme descriptor`.
+
+Если CSS не применился:
+
+- проверьте `css_file` и URL `/webapp-theme-css/<key>/<css_file>`;
+- убедитесь, что файл меньше 512 KiB;
+- начинайте селекторы с `.theme-key-<key>`;
+- откройте `/home?theme_preview=<key>` в новом окне, чтобы исключить сохраненный старый выбор.
+
+Если ассеты не грузятся:
+
+- используйте путь `/webapp-theme-assets/<key>/<path>`;
+- проверьте расширение: `png`, `jpg`, `jpeg`, `gif`, `webp`, `svg`, `ico`;
+- размер каждого файла должен быть до 1 MiB;
+- путь не должен содержать пробелы, кириллицу или `..`.
