App Store 截图框——冥想 App

生成一张 4:5 竖版 1024x1280 的移动应用商店宣传截图风格海报，面向虚构冥想应用品牌「Guided breathwork. Sleep sounds. No subscription.」。全出血背景从浅黎明蓝渐变到暖薰衣草紫。顶部 20% 使用中文无衬线大标题「10分钟安然入睡」，副标题「呼吸练习｜助眠白噪音｜无需订阅」。画面中央是一台无品牌现代全面屏手机样机，手机必须保持自然 iPhone 竖屏比例，不能拉宽、压扁或变形；屏幕内展示极简音频播放器界面：靛蓝波形、月亮图标、计时器「08:43」、播放按钮。设备下方三组中文功能标签：「睡前故事」「呼吸训练」「自然声音」。底部柔靛蓝行动条，白色圆角按钮写「免费下载」。整体安静、疗愈、类似高端水疗，所有可见文字必须为中文，不出现真实平台名称、真实应用图标、水印或外部标志。

A single App Store screenshot promotional frame sized at 1290x2796 px (iPhone 15 Pro Max portrait), for a fictional meditation app called Stillwave. The background is a full-bleed soft gradient from pale dawn-blue at top to warm lavender at the bottom. In the upper 20% of the frame, a clean sans-serif heading reads "Fall Asleep in Under 10 Minutes" in slate blue, with a thinner subtitle beneath: "Guided breathwork. Sleep sounds. No subscription." Centered in the frame, a realistic iPhone 15 Pro mockup shell (device frame only, Titanium Natural finish) displays an app screen showing a minimal audio player UI with a large waveform visualization in indigo and soft pulse animation frames, a moon icon, and a timer reading "08:43". Below the device, three small feature icons with labels: a moon glyph and Sleep Stories, a waveform glyph and Breathwork, a leaf glyph and Nature Sounds. Bottom CTA strip in soft indigo: "Download Free" in white rounded button. The overall feel is spa-calm and restful.
