不依赖生成文字的产品海报

Editorial product poster featuring {{subject}}. Palette: {{palette}}. Mood: {{mood}}. One dominant subject, clean silhouette, restrained set design, textured surface, directional studio lighting, generous empty space above the subject for later typography. Keep the composition readable at thumbnail size. No generated lettering, no watermarks, no extra product copies. This is a concept composition, not a factual product photograph.
