Póster comercial vibrante para una marca de parches para bajar la fiebre

Generate a commercial poster for Kobayashi Pharmaceutical cooling gel sheets with ultra-saturated, vibrant energy. In the exact center of the image, place a highly realistic portable pouch of Kobayashi Pharmaceutical cooling gel sheets - a mini stand-up pouch with a resealable zipper, ice-blue matte surface, white brand logo, transparent window showcasing the blue cooling sheets, premium glossy printing, and commercial-grade product rendering. The background is a hand-drawn illustrated energy universe: a circular burst erupting from behind the pouch, with flying blue cooling sheets, splashing ice crystals, cooling ripples, snowflake shapes, refreshing energy trails, comic-style impact explosions, bouncing arcs, lightning bolts and stars, smiley doodles, speed lines, and mini snowflakes, all with thick black outlines in pop art style. The dominant background color field is ice-crystal blue, with the illustration bursting in pure white and mint green. The typography is playful and rounded: main title "Kobayashi Pharmaceutical," subtitle "COOL PACK, FEVER DOWN," call-to-action "OPEN. STICK. COOL.," and Chinese artistic text "随手一袋，即刻降温." Overall mood: playful, ultra-saturated, dynamic, youthful, pop art, cooling, and full of energy. Aspect ratio 3:4, 8K premium commercial quality. Prohibited: soft pouch packaging, paper boxes, realistic backgrounds, dull colors, weak dynamism, cluttered layouts, low saturation, blurry products, cheap cartoon styles, excessive text, and gloomy atmospheres.
