Japanese Golden Egg Concept Presentation Slide

A modern presentation slide and social media graphic in 16:9 format on a dark charcoal-black background (#181818) with generous negative space on the right. Top left text features clean Japanese typography 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 and remaining characters in regular white. Below the headline on the left sits a dark navy-black rounded rectangular card with a subtle border and soft drop shadow. Inside the card is a 4-column by 3-row grid showing 12 distinct [golden egg] concept renderings: 1) glossy smooth upright gold egg with bright highlight, 2) stylized oval egg with a raised rim icon outline, 3) low-poly faceted gemstone egg, 4) smooth metallic egg on a soft contact shadow, 5) flat bright yellow-gold egg with bold white highlight, 6) textured brushed-gold egg, 7) polished reflective egg with a sparkle star flare, 8) dark luminous egg with vivid rim lighting, 9) wide squat golden egg, 10) elongated tall slender gold egg, 11) deep bronze-gold reflective egg, 12) minimalist matte yellow-gold egg silhouette. Lower left text reads: "[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 clause in bold white. A semi-transparent circular down-arrow UI button floats near the lower right.
