/**
 * Демо «photo»: фотограф Вера Лисицына, портфолио.
 *
 * Галерея: чистый чёрный, белый текст, серые подписи, никакого цветного
 * акцента - цвет даёт только фотография. Тонкий шрифт, меню строчными,
 * вместо кнопок - тонкая рамка. Снимки без скруглений и теней.
 * Мобильная вёрстка первая, медиазапросы собраны у своих блоков.
