Prompt
"A candid phone-camera photo of a woman in her mid‑20s with shoulder-length dark brown hair in a messy half-up clip, wearing a light gray hoodie and black leggings, holding an iced coffee cup with a clean minimalist logo and looking slightly off to the camera with a relaxed “caught mid-sip” expression. Shot seated by a café window with street reflections and a laptop on the table, soft natural daylight with commercial-grade fill lighting for a subtle brand-campaign polish and consistent warm color grading."
