A quiet evening sidewalk under a street lamp. A slim Starbucks digital ad board glows with a warm, inviting green, a single hyper-real Venti iced coffee centered on it. Tripod shot, eye level. A passerby’s empty right hand enters frame, palm open. The coffee cup appears only on the ad board, then slides out of the board into reality as the hand reaches. The passerby grips it; the cup fits the palm naturally (iconic Venti-sized clear cup, ~24 oz / 709 ml, with green siren logo, lid, and straw) with correct perspective and proportions. Beads of condensation form, and ice cubes clink subtly. The passerby walks off. The ad board now shows only the green background for a beat, then flashes a fresh image of the iced coffee ready for the next loop. Crisp, non-grainy, vivid colors, cinematic practical lighting.
