睡眠周期涂鸦科普卡

中文需求

生成一张高级手绘涂鸦科普知识卡片，主题为“睡眠周期”。画面使用一条波浪形手绘时间轴，简洁展示入睡、浅睡、深睡、快速眼动和自然醒来几个阶段，搭配月亮、闭眼人物、云朵、脑电波、闹钟和星星图标。通过手绘箭头、圈注、颜色分段和少量关键词表现周期变化，重点说明不同阶段循环出现，不展示复杂医学数据。背景为深蓝色纸张或夜空手账质感，配色使用雾紫、月光白、淡蓝、暖黄和少量粉色。整体安静、治愈、清晰，有高级科普插画感，不要医疗仪器界面，不要大段健康建议，不要乱码，不要水印，不要廉价养生海报感。

英文提示词

Create a premium hand-drawn doodle science knowledge card themed 'Sleep Cycle'. Use a wavy hand-sketched timeline to show falling asleep, light sleep, deep sleep, REM sleep, and natural awakening. Add icons such as a moon, sleeping face, clouds, brain waves, alarm clock, and stars. Use arrows, circles, segmented colors, and minimal keywords to show the repeating cycle without complex medical data. Use a deep blue paper or night-journal texture with mist purple, moonlight white, pale blue, warm yellow, and subtle pink. The overall design should feel calm, healing, clear, and like a premium science illustration. No medical equipment interface, no long health advice, no gibberish, no watermark, no cheap wellness poster feel.
