Captivating Japanese Golden Egg Slide

Create a dark presentation style social media image in Japanese about golden egg design variations. Canvas: wide horizontal 16:9 ish crop, black/charcoal background (#181818), clean modern typography, generous negative space on the right. Top text: place a large Japanese sentence near the upper left reading 「まず imagegenで作った金の卵12案 です。」 with “imagegen” and “金の卵12案” in bold white, the rest in regular white. Main visual: below the headline on the left, draw a rounded rectangular dark navy black card with a subtle border and soft shadow. Inside the card show exactly 12 golden egg designs arranged in a 4 column by 3 row grid. The 12 eggs are: 1) glossy smooth upright gold egg with bright highlight, 2) oval egg with raised rim/outline like an icon, 3) faceted low poly gemstone egg, 4) smooth metallic gold egg standing on a small shadow, 5) flat bright yellow egg with large white highlight, 6) textured/brushed gold egg, 7) glossy gold egg with a star sparkle on the upper right, 8) dark glowing gold egg with bright rim light, 9) squat round golden egg, 10) tall narrow smooth gold egg, 11) darker bronze gold reflective egg, 12) simple matte yellow gold egg silhouette. Bottom text: place a long Japanese sentence across the lower left reading 「それを参考に、ファームのコード描画プリミティブで近似する12案 を作りました。」 with the central phrase 「ファームのコード描画プリミティブで近似する12案」 in bold white and the rest in regular white. Add a semi transparent circular down arrow overlay near the bottom center right, like a social media viewer control. Visual style: clean screenshot like composition, high contrast, realistic glossy gold rendering for the eggs, subtle card border, no extra logos or watermarks. Customizable text slots: top sentence may use {argument name="top Japanese text" default="まず imagegenで作った金の卵12案 です。"}; bottom sentence may use {argument name="bottom Japanese text" default="それを参考に、ファームのコード描画プリミティブで近似する12案 を作りました。"}; main object may use {argument name="object theme" default="golden egg"}.
