Japanese AI Creator Studio Banner

Create a polished Japanese promotional website hero banner for an AI creator community, in a clean modern tech-advertising style with a soft pastel blue, lavender, pink, and white palette. Wide 16:9 composition. On the left, place a gradient triangular abstract logo and the Japanese brand name {argument name="brand name" default="AIクリエイターズ・スタジオ"} at the top, followed by a thin horizontal divider line with a small sparkle in the middle. Below that, a very large bold Japanese headline in 2 lines: first line in dark navy, 「AIで、もっと自由に」, second line in large gradient letters from cyan to purple to pink, 「創る・学ぶ・つながる」. Under the headline, add a short Japanese subheadline with sparkle marks, 「AIを使ったクリエイティブの可能性を広げるメンバーシップコミュニティ」. On the right half, create a collage of 6 rounded-rectangle visual cards showing AI-generated creative examples: 1 large dreamy portrait of a woman in profile surrounded by flowers and butterflies in ethereal purple light, 1 small cyberpunk city nightscape with a lone figure, 1 small close-up portrait of a fluffy cat, 1 small luxury cosmetic bottle labeled “AI STUDIO”, 1 small bright seascape or flower-field landscape with a woman in white, and 1 large tablet drawing device on a desk with a stylus, plus a coffee mug and plant nearby. Add a circular gradient badge overlapping the right side with bold white Japanese text {argument name="badge text" default="一緒に創造の未来をつくろう！"}. Across the lower middle, place a translucent white rounded feature panel containing exactly 5 equal columns with thin separators and pastel line icons. Each column has an icon, a bold Japanese title, and a smaller 2-line description. The 5 titles are: 「限定コンテンツ」, 「実践プロンプト＆テンプレート」, 「メンバー限定コミュニティ」, 「最新情報をいち早くお届け」, 「メンバー限定特典」. Use fitting icons for book, monitor, chat bubble, light bulb, and gift. Add concise Japanese descriptions beneath each title. At the very bottom, add a dark navy footer strip with a large Japanese call-to-action sentence in white and pink-purple gradient accent text, {argument name="footer text" default="AIを味方に、あなたの『創りたい』をカタチに。さあ、一緒に創ろう！"}. Overall look: premium startup landing page, glossy soft lighting, subtle sparkles, glassmorphism panels, clean typography, Japanese text rendered accurately, highly legible, visually balanced, professional social media thumbnail quality.
