Cool-Tone Idol Editorial Wallpaper

Vertical 4:5 mobile wallpaper in a digital collage and magazine editorial style. A female K-pop idol faces the camera and showcases an off-shoulder striped knit outfit with edgy platform leather boots. Use a silver, charcoal, and deep-black palette with a clean white cutout border around her. Place July 2026 calendar typography at the top, a desaturated urban street background below, and a layered Polaroid in the lower right with handwritten “Happy Birthday”. Cinematic lighting, muted moody color, film grain, artistic fashion-spread composition, and ultra-detailed finish.
