/* X World Music — лендинг. Основа — стиль X-WORLD Partner (те же темы, шапка, скругления, шрифт Golos Text),
   плюс музыкальный акцент: спектр из пяти фирменных цветов X-WORLD и широкий шрифт Unbounded для названия.
   Раскладка: шапка → «сцена» со спектром на всю ширину → лента-пример → два способа загрузки → преимущества → вход. */
