แบนเนอร์โฆษณา SaaS ของญี่ปุ่นในเวลากลางคืน

A polished square Japanese digital advertising banner for an AI e-commerce optimization tool, split into 2 main visual zones by a bold diagonal blue divider running from upper center to lower center-left. On the left third, show a realistic nighttime home-office scene with 1 tired young woman sitting at a desk, Show every face clearly with natural, detailed facial features, resting her head on one hand while looking at an open laptop. Warm desk-lamp lighting illuminates her and the desk, with a mug in the foreground, scattered papers, shelves and a wall clock softly out of focus in the dark background, creating a late-night overwork mood. On the right two-thirds, place a deep blue gradient promotional panel with subtle financial-growth graphics in the background: 1 ascending line chart with arrow and 4 vertical bar-chart columns in a lighter transparent blue near the top right. Fill this panel with bold oversized Japanese headline text in white with strong drop shadow, stacked across 4 lines: {argument name="headline text" default="深夜の\nサムネ入れ替え、\nもう自動化\nできます。"}. Beneath it, add 1 subheadline line in white reading {argument name="subheadline text" default="楽天専用 A/Bテスト自動化ツール"}, accented by a thin cyan underline. Below that, place a horizontal process strip containing 3 white rounded-corner cards connected by 2 cyan right-pointing arrows. Card 1 shows 2 handbag thumbnails side by side labeled exactly 2 items: "サムネA" and "サムネB", with blue and gray percentage badges reading "64.3%" and "35.7%", and a centered "VS" between them. Card 2 shows 1 selected black handbag thumbnail, a small gold crown icon above it, gray checklist lines to the right, and a turquoise confirmation checkmark badge, with a small Japanese heading indicating automatic optimization. Card 3 shows 1 simple analytics chart with axes, several blue bars, 1 pink upward trend line, small Japanese labels for sales and CTR trend, and a pink result figure "+47.2%" at the lower right. At the bottom left, add 1 bright pink rounded promotional badge with bold white Japanese text on 2 lines: {argument name="offer text" default="1週間\n無料トライアル"}. At the bottom right, add 1 dark navy rounded logo bar containing a simple white geometric emblem and the brand name {argument name="brand name" default="Easy Creative"} in bold white sans-serif. Use a clean modern SaaS-ad aesthetic, high contrast, crisp typography, glossy UI cards, subtle shadows, and a professional conversion-focused layout sized 1:1.
