Plakat Promocyjny Onboardingu Japońskiej Aplikacji

A clean modern app-promo poster on a very pale mint-blue background, centered and vertically composed like a landing page visual for a Japanese inventory mobile application. At the top, a small rounded white pill logo with a soft drop shadow reads "[Zaiko]" in green text. Beneath it is a small outlined pill badge with a blue dot and the text "02 初回ガイド". Below that is a large bold Japanese headline in dark navy: "[初回ガイドで、すぐ使える。]", followed by a smaller gray subtitle: "起動したら管理の流れをやさしく案内". Under the subtitle are three small rounded white category chips with soft shadows, evenly spaced: "サンプル" with a green dot, "使い方" with a blue dot, and "すぐ開始" with a dark dot. In the center, a realistic modern smartphone mockup front view with thin black bezels, subtle glass reflections, and a soft ambient blue glow beneath. The phone screen displays an app interface with iPhone-style status icons and a green top bar reading "[Zaiko]" in white. Over a dimmed background UI sits a centered white onboarding modal card with rounded corners and a soft drop shadow. Inside the modal: a pale green circular badge with a green cube icon at top, bold Japanese welcome headline "Zaikoへようこそ！", a subtitle "消耗品管理アプリ", and description text "このアプリは、おうちの消耗品を管理するよ！". Below is a light gray rounded list container showing three sample inventory items with small icons on separate lines: "トイレットペーパー", "シャンプー", and "洗剤", followed by a highlighted note: "『そろそろ買わなきゃ！』を教えてくれるから、買い忘れなし ✨". At the bottom of the modal is a large rounded green primary button labeled "[使い方を見る]" with a book icon, and a muted text link "スキップ" underneath. Subdued background UI shows a green header and a bottom navigation bar with three tabs: "ホーム", "買い物リスト", and "設定". Beneath the phone mockup is a wide rounded blue banner card with a soft shadow and a centered white pill badge reading "[はじめての設定も迷わない]". Polished Apple-style SaaS marketing aesthetic, clean vector UI elements, crisp typography, friendly and trustworthy feel.
