Luxury Natto Product Banner

Create a luxurious Japanese advertising banner for {argument name="product name" default="NÉBA"}, premium fermented soybeans/natto, in a dramatic dark purple and black studio setting with radiant gold light trails, glittering particles, and an elegant high-end cosmetics/jewelry aesthetic. The composition is a square promotional visual: on the right, a transparent faceted crystal octagonal jar is open, overflowing with glossy amber-brown natto beans; long sticky golden strands stretch upward and swirl like luminous silk threads, with individual beans suspended in the strands. The jar has a dark plum label with gold typography reading {argument name="product name" default="NÉBA"}, small Japanese premium-product copy, and a refined floral emblem. Behind it, the open crystal lid stands upright with the same gold logo, resembling a luxury perfume or gem case. On the lower left, show a bowl of white rice topped with natto, green onion rings, a dab of mustard, and a dramatic splash of dark sauce shaped like a crown. Use large elegant Japanese headline text on the left reading {argument name="headline text" default="ねばりが、美学になる。"}, with the word for beauty in oversized gold calligraphy and the rest in white. Below it, include smaller Japanese body copy reading {argument name="body copy" default="糸まで、美しい。架空のプレミアム納豆、誕生。"}. Add a large serif Roman product title “NÉBA” with the subtitle “PREMIUM FERMENTED SOYBEANS” beneath it. At the bottom right, place a slim dark rectangular call-to-action button with a gold border, Japanese text reading {argument name="call to action" default="気になるなら、まず一粒。"}, and a right arrow. Overall style: ultra-polished luxury food commercial, hyper-detailed 3D product rendering, glossy reflections, faceted glass refraction, cinematic gold rim lighting, premium Japanese typography, intentionally over-the-top and not practical as an informational banner.
