Use case: stylized-concept
Asset type: prompt-reconstruction stability test for a vertical editorial poster

Create a vertical 3:4 flat scanned-paper poster on warm cream, lightly aged uncoated stock. Center one abundant bunch of ripe grapes inside a large ornate rococo oval frame or serving-platter border. The grapes and frame should occupy about 76% of the page, with a graceful diagonal stem entering from the upper right. Place the title in a sweeping diagonal arc across the upper-left area, close to the top of the frame.

Render the grapes, stem, cast tonal bed, and elaborate frame entirely in one deep velvet-violet ink. Use fine micro-dot halftone, tiny square-pixel mesh, antique copperplate/engraving linework, stippled highlights, broken ink coverage, and density-based shading. Each grape should remain round and luminous through white paper highlights and dense-to-sparse violet dots, not smooth photography. The rococo border needs symmetrical scrolls, curls, shell motifs, and delicate worn linework. Keep everything flat, printed, slightly misregistered, softly scanned, and tactile with paper fibers and toner dust.

Render the exact title "Velvet Grapes" once, large and sweeping in an elegant calligraphic italic Didone serif across the upper left. Add these exact small monospaced/typewriter captions once each with sparse dotted leader lines: "ripe & bright" at upper right, "cool harvest" at mid-left, "sweet skin" centered along the lower frame, and "07.25" at bottom center. A few tiny ornamental fleuron marks are allowed. No other readable text.

Mood: strange luxurious fruit specimen, antique rococo plate meets modern Japanese editorial bitmap print. Avoid retro game pixel art, chunky pixels, game sprites, sticker art, cartoon fruit, smooth vector fills, watercolor, glossy food photography, multiple ink colors, gold metallic effects, 3D depth, cinematic lighting, dense collage, extra fruit species, extra text, repeated labels, logos, watermark, UI, CTA, product advertisement, and mockup photography.
