Minh Họa Kỷ Niệm Trên Điện Thoại Nắp Gập Cổ Điển

A standalone illustration of an open [silver-blue translucent flip phone] in a soft watercolor and anime concept-art style. On the phone's screen, naturally fitted inside the display gallery, is [the four-person summer group photo from the reference photo], showing a blue-haired girl, a black-haired boy, a brown-haired girl, and a brown-haired boy. The retro Japanese clamshell phone features an authentic keypad, hinge, worn translucent plastic texture with subtle scratches, and an attached blue star charm strap. Set against a clean pale white background with faint blue shadows and a few drifting translucent petals. No UI text, captions, frames, or extraneous graphic elements.
