一只实验瓶，让暖光与冷光在玻璃里相遇

Create ONE standalone original product photograph, landscape 3:2: a clear laboratory glass flask of pale blue liquid standing on a clean matte workbench. One warm amber beam from the left and one cool cyan beam from the right meet across the curved glass, yielding realistic highlights, meniscus and shadow. Controlled studio precision, subtle background gradient, crisp vessel silhouette, credible refraction, no labels, text, hands, logos, watermark, collage or multiple frames.

拍摄一只装有浅蓝液体的透明实验玻璃瓶，置于干净的哑光工作台。左侧一束琥珀暖光，右侧一束青蓝冷光，在弯曲玻璃上形成清楚高光；液面、折射和落影要合理。背景只有柔和渐变，保留瓶口与底座轮廓，没有标签、文字或其他器皿。
