New Chinese Trendy Cold Brew Tea Launch Poster

3:4 vertical promotional poster for a new Chinese trendy cold brew tea launch, New Chinese light luxury restrained aesthetic, color palette of matte dark green, soft off-white, warm metallic gold, full background with subtle rice paper texture, generous elegant negative space, faint minimal ink-wash Chinese mountain landscape accents at edges, modern clean grid layout, no tacky overly commercial e-commerce elements, overall sophisticated premium feel.
Central focal subject: visually appealing frosted clear cup of cold brew tea, visible curled oolong tea leaves inside, fresh sliced pomelo citrus pieces, glistening clear ice cubes, delicate touches of gold foil on the cup rim and scattered lightly around the drink base, soft diffused natural side lighting, slightly elevated perspective so the drink stands out clearly.
Clear promotional typography hierarchy, all text is sharp and legible, elegant Chinese typography aesthetics, traditional calligraphic serif font for main headers, clean minimalist sans serif font for body text, numbers and prices, no distorted or blurry characters, text properly spaced and aligned without overlapping.
