+# План редизайна фронтенда Game Marathon
+
+## Концепция дизайна
+
+**Стиль:** Минималистичный геймерский дизайн
+- Темная база с неоновыми акцентами (cyan/purple/pink градиенты)
+- Glitch эффекты на заголовках и при hover
+- Glassmorphism для карточек (blur + transparency)
+- Subtle grain/noise текстура на фоне
+- Геометрические паттерны и линии
+- Микро-анимации везде
+
+**Цветовая палитра:**
+```
+Background:    #0a0a0f (почти черный с синим оттенком)
+Surface:       #12121a (карточки)
+Border:        #1e1e2e (границы)
+Primary:       #00f0ff (cyan неон)
+Secondary:     #a855f7 (purple)
+Accent:        #f0abfc (pink)
+Success:       #22c55e
+Error:         #ef4444
+Text:          #e2e8f0

+- Discord dark theme
+- Valorant game UI
+- Steam profile pages
+- Twitch streaming UI
+- Epic Games Store

+
+## Технические заметки
+
+**Framer Motion:** Использовать для page transitions и сложных анимаций
+**CSS:** Использовать для простых transitions и hover эффектов
+**Tailwind:** Основной инструмент для стилей
+**Custom Hooks:** useAnimation, useGlitch для переиспользования логики

+
+<p>1.2. Сервис предоставляет Пользователям следующие возможности:</p>
+<ul>
+<li>Создание и участие в игровых марафонах</li>
+<li>Получение случайных игровых заданий различной сложности</li>
+<li>Отслеживание прогресса и статистики участников</li>
+<li>Участие в специальных игровых событиях</li>
+<li>Получение уведомлений через интеграцию с Telegram</li>
+</ul>
+
+<p>1.3. Сервис предоставляется на условиях «как есть» (as is). Администрация не гарантирует, что Сервис будет соответствовать ожиданиям Пользователя или работать бесперебойно.</p>
+
+<hr class="my-8 border-dark-600" />
+
+<h2>2. Регистрация и учётная запись</h2>
+
+<p>2.1. Для доступа к функционалу Сервиса необходима регистрация учётной записи. При регистрации Пользователь обязуется предоставить достоверные данные.</p>
+
+<p>2.2. Пользователь несёт полную ответственность за:</p>
+<ul>
+<li>Сохранность своих учётных данных (логина и пароля)</li>
+<li>Все действия, совершённые с использованием его учётной записи</li>
+<li>Своевременное уведомление Администрации о несанкционированном доступе к аккаунту</li>
+</ul>
+
+<p>2.3. Каждый Пользователь имеет право на одну учётную запись. Создание дополнительных аккаунтов (мультиаккаунтинг) запрещено и влечёт блокировку всех связанных учётных записей.</p>
+
+<p>2.4. Пользователь вправе в любой момент удалить свою учётную запись, обратившись к Администрации. При удалении аккаунта все связанные данные будут безвозвратно удалены.</p>

+
+<p>3.3. Организаторы марафонов несут ответственность за соблюдение правил в рамках своих мероприятий и имеют право устанавливать дополнительные правила, не противоречащие настоящему Соглашению.</p>
