/* Веб-каталог образов. Направление: тихая «фотобумага» — цвет несут сами фото, интерфейс спокойный.
   Тёплая нейтральная шкала, один акцент (тёмная сиена) только для ссылок и фокуса, заголовки с засечками, мелкие цифры как номера кадров.
   Выкладка: немного крупных осмысленных групп (П. Браун, «Эстетический интеллект»); все карточки тем одного размера и на одной линии. */
