窗前思考的少女：咖啡馆里的数学诗意

A cinematic, photorealistic scene of a thoughtful young woman with wavy auburn hair sitting alone at a wooden café table next to a large glass window. Warm golden sunlight softly illuminates her face as she rests her head on her hand, gazing out the window with a calm, pensive expression. The image is shot from outside the café through the glass, with gentle reflections, light bokeh, and a slightly blurred background creating a dreamy atmosphere. Handwritten white chalk-style mathematical equations are floating on the window glass around her, as if she is thinking about them: integrals, limits, algebraic formulas, a quadratic graph, trigonometric identities, and E = mc². The equations look lightly sketched, semi-transparent, and artistically placed without blocking her face. The mood is intellectual, introspective, and peaceful.
