   InCloud — единый общий CSS-контур сайта.
   Порядок подключения на странице:
   assets/tailwind.css → assets/incloud.css → assets/site.css → assets/pages/<page>.css
   Этот файл загружается последним из общих стилей: он единственный источник
   design tokens и целевых общих компонентов (.container, .section, .card,
   .icon-tile, .hero, .metric-strip, .lead-form, .faq).
   Структура файла:
     1. Design tokens
     2. База
     3. Layout: контейнер, шапка, подвал, навигация
     4. Компоненты: секции, типографика, кнопки, карточки, hero, формы, FAQ
     5. Контактная секция (.site-contact) и служебные блоки
     6. Продуктовые блоки (.product-*, hero-панели, калькулятор)
     7. Page-specific правки и legacy-совместимость

   7. Совместимость со старыми классами (временно, до миграции страниц)

   Целевые компоненты уже применяются к legacy-классам через сгруппированные
   селекторы выше:
     .container       ← .site-wrap, .astra-wrap, .cs-wrap, .pa-wrap
     .section         ← .astra-section, .cs-section, .pa-section
     .section-title   ← .astra-heading, .cs-heading, .pa-heading (и h2.text-3xl)
     .section-copy    ← .astra-copy, .cs-copy, .pa-copy
     .card            ← .product-card; частично .service-card, .terminal-card,
                        .astra-service, .advantage-card
     .icon-tile       ← .product-icon
     .hero            ← .hero-gradient, .astra-hero, .cs-hero, .pa-hero
     .metric-strip    ← .site-proof
     .faq / .faq-grid ← .product-faq / .product-faq-grid
     .lead-form       — новый компонент; .astra-form, .cs-form, .pa-form,
                        .terminal-form переводятся при миграции страниц

   Page-specific классы (.dc-*, .sla-*, .terminal-*, уникальные .cs-* и
   .pa-*) уже вынесены в assets/pages/<page>.css и загружаются после
   этого файла. В общие селекторы их не включаем: у них свои значения,
   и досрочный alias изменил бы визуал. По мере унификации страниц
   (план .devin/plans/html-unification.md) старые селекторы удаляются.
