美甲沙龍季節特賣主視覺（粉彩微距平拍風）

prompt

Create a square 1:1 social ad hero for a nail salon's {season} promotion. Top-down macro flat lay on a {base_color} pastel surface: one elegantly manicured hand at center showing {nail_style} gel nails, surrounded by neatly arranged polish bottles, dried flowers and acrylic charms in a loose grid. Soft diffused daylight, shallow depth of field, glossy nail reflections, editorial beauty-magazine feel. Keep the upper 25% as clean negative space — a safe margin reserved for the headline '{offer_text}' and the salon logo. No text rendered in the image, no brand labels on bottles. High-detail skin texture, realistic photography, crisp color grading.
