Cinematic vertical still, no logos no brand marks no readable product names. Dual-path creative duel metaphor: left half cool cobalt studio light, precise architectural interior with crisp glass reflections and calm controlled mood; right half warm amber volumetric haze, painterly illustration energy with soft dreamy depth. Center seam is a thin vertical razor of white light splitting the frame. Single anonymous creator silhouette at the seam facing away, holding a glowing blank tablet. Ultra photoreal mixed with subtle illustration bleed on the warm side. Dramatic contrast, high detail, Instagram 9:16 safe center composition, no text overlays, no watermarks, no UI.
