/* PicSeller 2.0 — стили модуля «Сайт: создание» (js/screens/sitebuild.js): #/site/new, #/site/builder. Классы только с префиксом sb-.
   Выделение секций в конструкторе масштабируется через --sb-k (тот же приём, что --pv-k в base.css).
   Module "sitebuild" styles. Use only sb--prefixed classes; tokens and components come from base.css.
   Сайт бренда в предпросмотре всегда в своих цветах, интерфейс вокруг — в токенах (светлая и тёмная тема).
   The brand site keeps its own colours; the UI around it uses tokens (light and dark themes). */
