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 single pale ivory iris flower captured as an extraordinary flatbed scanner / xerographic botanical study against dense velvety black. Flower enlarged on the right, its folded petals resolving into silver toner grain, coarse-to-fine dot breakup and luminous scanned edges. Slight analog duplication shadow along one petal only. Thin stem descends to bottom right. Left 60 percent uninterrupted near-black paper. Beautiful eerie monochrome editorial craft, neither a colorful floral photograph nor vector clip art. No vase, no text, no extra flowers. 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.
