/imagine prompt: Design a high-end horizontal banner for a luxury skincare brand featuring a glass serum bottle centered on a soft marble pedestal, surrounded by delicate water ripples, silk fabric, and faint botanical elements. The background should be elegant, minimal, and airy with cream, gold, and pearl tones. Use soft studio lighting, realistic reflections on the bottle, shallow depth of field, and premium editorial styling. Add subtle glowing highlights and refined shadow falloff. Leave generous clean space on the right side for headline and product copy. The image must feel expensive, modern, clean, and commercially polished. No clutter, no extra objects, no text, no watermark. Aspect ratio 16:9.
