Prompt de IA para banner vertical 9:16 estilo historia de startup

9:16 vertical format, LP main visual / story style. A warm, natural, and organic banner that tells the story of a first-year startup journey. The overall impression should be encouraging, hopeful, and grounded — with a sense of growth and hands-on effort. Background: soft beige wall with gentle wood grain texture, warm natural sunlight coming from upper left, a few small green potted plants on a wooden desk at lower right. Color palette: beige, soft brown, muted olive green, and a touch of warm white. Visual elements: a small hand-drawn style calendar with a circled date, a coffee cup with steam, a simple wooden frame with a tiny seedling inside, and subtle hand-lettered arrows pointing upward. Title (top, large): 「起業1年目の軌跡」. Main headline (center, bold): 「挑戦の先に」. Person: no real person — a simple, friendly vector silhouette of a person sitting at a desk with laptop, seen from behind or side, wearing a casual jacket, stylized but not realistic. Additional text: bottom left small note 「失敗から学んだこと」. Layout: hierarchical — title top, person center-right, headline center-left, plants and desk elements bottom edge. Text: large, bold, high contrast (white text with dark brown outline/background), no extra English, no logos, no watermarks. Only the specified Japanese text exactly as written. Do NOT add any other text, URL, logo, or watermark.
