Goal: Create a luxurious Japanese seminar advertisement banner for {argument name="seminar topic" default="Claude Code slide creation course"}, styled like a premium winter campaign visual for social media.
Canvas: Wide horizontal 16:9 banner, approximately 1200×675 px. Use a bright ivory, champagne-gold, and black color palette with glossy metallic effects, high contrast typography, and elegant holiday sparkle details.
Layout: Split composition with text-heavy promotional copy on the left two-thirds and a confident female presenter on the right third. The background is white-to-cream with soft bokeh lights, gold glitter, snowflake ornaments, tiny starbursts, thin diagonal gold accents in the corners, and subtle laurel decorations. Add a thin decorative gold frame feeling without enclosing the entire image.
Top labels: Place exactly 2 black-and-gold beveled badge tabs near the top: left badge with a diamond icon and the English text “AI SLIDE SEMINAR”; right badge with a crown icon and the English text “CODEX LESSON”.
Main text content: Use large premium Japanese typography with strong hierarchy. The main headline reads 「圧倒的に」 in huge gold serif characters, followed by “Claude Code” in very large elegant black serif letters, then 「スライド作成講座」 in bold black Japanese lettering. Below, add a gold ribbon banner with a clock icon and the text 「今日の2時間で」. Under that, place an enormous gold “10” and the phrase 「枚構成に変わります」 in black and gold, with small gold laurel branches around it.
Right-side subject: Show a stylish adult woman presenter from about mid-thigh upward, standing with arms crossed, wearing a fitted black blazer over a black top, delicate gold necklace, bracelet, earrings, and long wavy brown hair. Her face should be intentionally covered by a vertical soft brown rectangular blur/mosaic block, while the hair, outfit, and jewelry remain sharp and realistic. She should look elegant, professional, and luxurious.
Right-side callout: Across the woman’s torso, place a slanted black glossy banner with gold trim and sparkles. It reads 「初心者でも強い。」 with 「強い」 emphasized in gold. Beneath it, add three centered lines of small white Japanese copy: 「AIで資料作成を効率化し、」, 「スライドもLPも」, 「会話で形にする実演講座」. Add a small decorative gold flourish below.
Visual style: Premium editorial ad design, realistic portrait photography mixed with ornate Japanese flyer typography, metallic gold foil text, black ink calligraphy contrast, winter snowflake motif, glitter particles, soft lens flare, crisp commercial composition.
Constraints: Preserve exactly 2 top badge tabs, 1 gold ribbon banner, 1 large numeral “10”, 1 slanted black callout banner, and 1 blurred-face female presenter. Keep all text legible and in the same hierarchy; do not add extra logos, watermarks, QR codes, or unrelated icons.
