Yandex RSY square banner (1:1), dynamic duo lifestyle composition. Electric teal-to-deep-blue gradient background, festive but clean. ONE focal moment: two friends side by side — man and woman, 25-40yo, both grinning wide, arms around each other's shoulders, captured at a comedy/quiz night, neon accent lighting. Large bold "2+1" graphic element in bright yellow floating upper-left as visual hook. Center-bottom: solid dark rectangle overlay band. Centered bold white Russian text: "Берите гостя +1 на любое событие". Heavy weight sans-serif, perfectly spaced, 32% image height. Emotion: friendship, fun, social invitation. Yandex-Ads-ready. ТЕКСТ НА БАННЕРЕ: "Берите гостя +1 на любое событие"
