Generate ONE new standalone website companion background. Aspect ratio 9:16; tall PORTRAIT, height much greater than width. The supplied image is a STYLE REFERENCE, not an image to copy or crop. Maintain its medium, material realism, art direction, visual family and quality. Theme: A striking handmade paper-cut alpine mountain range using thick chalk-white rag paper, charcoal paper and one deep ultramarine layer. Jagged sculptural ridgelines stacked low in the right half, hand-cut irregular paper edges and fine fibers visible, tiny believable cast shadows under soft raking daylight. Huge empty warm ivory paper sky across top and left. Physical photographed paper craft, graphic editorial minimalism, extraordinary clean silhouette, not a digital 3D landscape. VARIATION INSTRUCTIONS (take precedence over original theme positioning or palette): Create a TALL PORTRAIT image composed specifically for mobile: main visual concentrated in bottom 45%, upper 50% quiet space. Preserve the medium and palette. New composition, not a center crop. This must be a distinct generated composition. No words, letters, numbers, interface, watermark, border or collage. Highest native detail. Intended use: Mobile hero.
