Dynamic Pop Art Fever Patch Product Showcase

Please generate a hyper-saturated and energetic commercial poster for Kobayashi Pharmaceutical cooling patches. In the center of the screen, place a highly realistic portable bag of Kobayashi Pharmaceutical cooling patches—a mini self-standing bag with a zip-lock, ice-blue primary color matte surface, white brand logo, and a transparent window displaying the blue cooling patches, featuring high-end gloss printing and commercial-grade product rendering. The background is a hand-drawn illustrated energy universe: exploding in a ring from behind the bag, featuring flying blue cooling patches, splashing ice crystals, cooling ripples, snowflake shapes, cool energy trajectories, comic-style impact bursts, bouncing arcs, lightning stars, smiley face doodles, speed stripes, and mini snowflakes, with bold black outlines in a Pop Art style. The primary background color domain is ice crystal blue, with the illustration bursting in pure white and mint green. Playful and rounded fonts: 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 atmosphere: playful, high saturation, dynamic, youthful, pop art, cool, and full of energy. Aspect ratio 3:4, 8K high-end commercial quality. Prohibited: soft bag packaging, cardboard boxes, realistic backgrounds, dull colors, weak dynamics, cluttered layout, low saturation, blurred products, cheap cartoons, excessive text, dark atmosphere.
