Yandex RSY square banner (1:1), bold split-screen problem/solution composition. LEFT HALF: desaturated cold grey — lone figure looking bored, scrolling phone on empty couch, flat dull lighting. RIGHT HALF: vivid electric purple and warm amber — same figure laughing at a packed theatrical performance, confetti mid-air, stage lights blazing. Hard vertical dividing line between halves. Center-bottom: wide dark banner stripe spanning full width. Centered massive white bold Russian text: "Безлимит мероприятий в Москве 2000". High contrast, punchy, 32% image height. Yandex-Ads-ready. ТЕКСТ НА БАННЕРЕ: "Безлимит мероприятий в Москве 2000"
