/*
 * Лендинг «РЭМ Витол». Геометрия и цвета блоков — инлайн-стилями в партиалах, 1:1
 * с макетом Claude Design (materials/sog, README макета). Здесь — только то, что
 * инлайном не выразить: базовые правила, hover/focus, адаптив шапки, состояния
 * слайд-шоу, формы и лайтбокса. Hover-правила с !important, потому что перебивают
 * инлайн-стиль элемента.
