/*
 * ============================================
 * ПРИНЦИПЫ ДИЗАЙНА САЙТА - ОБЯЗАТЕЛЬНО К ИЗУЧЕНИЮ
 * ============================================
 * 
 * ВСЕ, КТО РАБОТАЕТ НАД ЭТИМ САЙТОМ, ДОЛЖНЫ СЛЕДОВАТЬ ЭТИМ ПРИНЦИПАМ:
 * 
 * 1. МИНИМАЛИСТИЧНЫЙ ДИЗАЙН НА УРОВНЕ APPLE
 *    - Чистые линии, много белого пространства
 *    - Минимум декоративных элементов
 *    - Фокус на контенте, а не на эффектах
 *    - Использование системных шрифтов Apple
 * 
 * 2. ЕДИНООБРАЗИЕ СТИЛЕЙ - НЕТ УНИКАЛЬНЫХ РЕШЕНИЙ
 *    - Каждое дизайн-решение должно повторяться минимум 2-3 раза
 *    - Использовать CSS переменные для цветов, отступов, размеров
 *    - Одинаковые элементы должны выглядеть одинаково
 *    - Нет визуального шума - только необходимые элементы
 * 
 * 3. ПРОФЕССИОНАЛЬНАЯ АДАПТАЦИЯ ПОД МОБИЛЬНЫЕ УСТРОЙСТВА
 *    - Mobile-first подход
 *    - Плавные переходы между breakpoints
 *    - Все элементы должны быть удобны на touch-экранах
 *    - Минимальные размеры для кликабельных элементов: 44x44px
 * 
 * ============================================
