一隻實驗瓶，讓暖光與冷光在玻璃裡相遇

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.

拍攝一隻裝有淺藍液體的透明實驗玻璃瓶，置於乾淨的啞光工作臺。左側一束琥珀暖光，右側一束青藍冷光，在彎曲玻璃上形成清楚高光；液麵、折射和落影要合理。背景只有柔和漸變，保留瓶口與底座輪廓，沒有標籤、文字或其他器皿。
