Royal Prince Potato Chips Package

Goal: Create a premium Japanese potato chips package design based on an illustration-world concept, turning a royal character into a colorful snack bag advertisement. Canvas: Front-facing vertical product package mockup, 3:4 aspect ratio, isolated on a clean white background. The bag should look like glossy crinkled plastic with sealed ridged edges at the top and bottom, subtle folds, highlights, shadows, and slight perspective bulging like a real snack bag. Package design: Use an elegant white, burgundy, and metallic gold color palette. The top and bottom bands are deep burgundy with gold trim lines; the main center area is pale white/cream with a faint palace or marble-column background. Add ornate gold flourishes, crown motifs, and premium European royal styling. Brand and main text: At the top center place a gold crown logo and the brand name {argument name="brand name" default="Reggbis"} with small Japanese reading beneath it. In the top-left corner add a vertical burgundy ribbon badge reading 「期間限定」. Across the upper center, add small copy reading 「白の王子様と味わう贅沢なひととき」. The largest central product name should read 「ポテトチップス」 in bold metallic-gold Japanese lettering. On the right, inside an ornate gold frame with a crown, write 「白の王子様の 焦がしバター コンソメ味」. Beneath it add smaller copy: 「芳醇なコクとバターの余韻が広がる、贅沢な味わい。」 Main subject: Show one elegant white prince character occupying the left and center of the package art. The prince has long pale-blond hair and wears a white military-style royal uniform with gold embroidery, epaulettes, decorative buttons, a high collar, lace cuffs, and a red cape draped over one shoulder. Pose him confidently with one hand on his hip and the other hand raised near his head. The face is intentionally covered by a plain rectangular censor-like beige blur, preserving the package aesthetic. Use {argument name="character theme" default="white prince"} as the core character concept. Food elements: Show exactly 4 food items in the lower-right foreground: 2 golden potato chips, 1 small round bowl of glossy brown consommé sauce, and 1 pat of butter melting on a yellow puddle. Chips should look crisp, lightly speckled, and appetizing, overlapping the lower part of the character and package. Badges and footer: Add one diamond-shaped burgundy-and-gold badge at the lower left reading 「国産じゃがいも 100% 使用」 with a small crown. Along the bottom burgundy band write “Premium Potato Chips” in elegant gold cursive. Add tiny Japanese disclaimer text at the bottom right, similar to product-package fine print. Visual style: Realistic commercial snack packaging mockup mixed with polished anime/cosplay illustration art, high-detail glossy plastic, luxury Japanese limited-edition product design, warm gold lighting, sharp typography, premium supermarket snack aesthetic. Constraints: Keep the design as a single potato chip bag only, no hands holding it, no extra products, no background scene outside the package, and make all Japanese text legible and positioned like authentic Japanese snack packaging.
