Frosty Green Lager Beer Promo With Coupon

[Format] Professional e-commerce product main image, square 1:1, chilled beverage promo style with a frosty photographic core. [Colors] Grey smoky backdrop with crushed ice and cold mist; green glass bottles; a violet gradient border frame around the whole square; a white coupon card with red numerals; a violet pill. [Layout] The bottles rise diagonally from the lower-left; ice piled at the base; the coupon tag anchored lower-right; no other type in the frame. Condensation beads catch cool highlights along the labels, and thin mist curls between the two bottle necks. [Subject] Two green swing-top lager bottles branded "Groellsch Premium Lager" with white-and-red labels, wire bails and porcelain caps, heavily beaded with condensation, standing in a bucket of crushed ice amid drifting cold fog. No people. [Headline] On the white coupon card: small caps "Coupon", then "50 yuan" as a huge red 50 with its currency mark, and "No minimum spend" beneath. Below the card a violet pill: "$1 coupon grab, valid today only". [Badges] The white coupon card is the single claim element; the violet gradient frame ties the composition together. [Mood] Ice-cold, fizzy and deal-driven; frosty grey-green photography wrapped in an energetic violet promo frame. The coupon tag dominates the lower-right so the deal message lands as fast as the cold-beer craving.
