Задумчивая женщина у окна кафе

Cinematic photorealistic shot of [a thoughtful young woman with wavy auburn hair] sitting alone at a wooden café table beside a large glass window. Warm golden sunlight softly illuminates her face as she rests her head on her hand, gazing outside with a calm, pensive expression. The camera is positioned outside the café looking in through the glass pane, capturing subtle reflections, warm bokeh, and a gently blurred background. Semi-transparent, handwritten white chalk-style [mathematical equations] float on the window glass around her—including integrals, limits, algebraic formulas, a quadratic graph, trigonometric identities, and E = mc²—artistically arranged without obscuring her face. The mood is [intellectual, introspective, and peaceful]. Shallow depth of field, natural lighting, warm cinematic color grading, soft film grain.
