促销倒计时贴图（Dreamina 官方 #12） prompt

Promotional offer with animated countdown. Subject: the brand product centered on a vibrant brand-color backdrop. Action: large animated digits tick down 5, 4, 3, 2, 1, then a clean reveal shot of the product. Scene: minimal studio set, glossy floor, soft floor reflection. Light: hard key from above-front, color-matched practical accent in brand hue. Camera: locked centered medium close-up, single slow push at the final beat. Style: high-energy retail commercial, crisp graphic feel. Audio: clean clock tick per number, single soft impact on the reveal, no voice. Constraints: avoid generating Chinese or Latin subtitle bars, only the deliberate countdown digits should appear, no watermark, no extra Logos.
