Design a studio product-photography style MOCKUP of a perfume or cosmetic bottle, 3:4 portrait aspect ratio, output size 1200x1600. FIXED LAYOUT (must match across every variant of this template): one centered glass-bottle silhouette occupying about half the frame height, fully visible with nothing cropped; a soft studio-lighting backdrop with a subtle gradient and a soft shadow beneath the bottle; a label area on the bottle body reserved for the brand/product name; a small, understated brand wordmark repeated at the very bottom of the frame. VARIABLE CONTENT for this specific example: bottle shape = a small amber-glass roller-bottle with a wooden cap, label brand/product name text = "Still Grove - Lavender Calm Roll-On", backdrop tone = warm neutral linen gradient, palette = amber and sage. Render the label brand/product name as real, legible, correctly spelled text on the bottle label. Do not add a watermark. Do not crop the bottle at the frame edges.
