Промо-баннер розыгрыша для соцсетей

A vibrant flat 2D social media promotional banner design filling the entire canvas. Centered in the composition, an open gift box with [Tonkotsu Ramen, Tea, Tissue Box] joyfully popping out, surrounded by floating celebratory ribbons and confetti stars. At the top, bold and cute rounded typography reads "[My Favorite Item Giveaway Campaign]". At the bottom, clear secondary text reads "[Follow & Repost]". Bright and cheerful color palette dominated by pastel pink, sunny yellow, and light sky blue. Clean, flat, uniform lighting with soft subtle shadows, modern pop graphic illustration style. No frames, no mockups, no wall backdrop, purely flat full-bleed digital banner artwork.
