## Steps
1. Pick a preset — In /app/image, choose Wallpaper (16:9 · 2K) for desktop or Story / Reel (9:16) for phone.
2. Describe the scene — Wallpapers work best with a clear subject off-centre and calm space around it — landscapes, skies, cities, fantasy scenes.
3. Go 4K if you need it — Pick Seedream 5.0 Lite and a 4K size (2304×4096 phone or 4096×2304 desktop) — or upscale any image up to 4K.
4. Download and set — Downloads have no watermark. Set it as your lock screen or desktop.

## In depth

### What makes a good wallpaper
A wallpaper sits behind icons, widgets and a clock, so it needs different things from a poster:
- One clear subject, placed off-centre or low in the frame.
- Calm areas where icons and the clock go — sky, water, soft shadow.
- No text in the image; your phone adds its own.
- Mood through light: dawn, golden hour, neon, moonlight.

### Getting the shape right
Generate at the shape you'll use. A 9:16 image cropped from a square loses most of the scene; a 16:9 wallpaper made at 16:9 keeps it. The presets set the shape for you, and the 4K sizes on Seedream 5.0 Lite match phones and monitors directly.

### Resolution and upscaling
Most phones look sharp at 1080×1920; high-end phones and 4K monitors benefit from 4K. If you already have an image you love, the Image Upscaler enlarges it up to 4K instead of generating again.
