/*
 * ProChef Tools — оформлення.
 *
 * Мова взята з інтро: майже чорна сцена, два конуси прожекторів згори, мокра
 * підлога з кольоровими відблисками і чотири «стихії» з кадру — вогонь,
 * лайм, вода й полуниця. Кожен інструмент отримує свою стихію акцентом
 * (--accent), решта — від порталу ProChef: волосяні лінії замість рамок,
 * капсульні кнопки, білий текст як основний колір.
