WaveVisual uses “template” in a couple of places. They are not the same thing.

• Wallpapers live in the Background tab. They are ready-made gradient images you tap to fill the background. They do not change your wave style or text.
• Design templates live in the Templates tab (and on wavevisual.com/templates). Each one is a full layout—wave style, colors, background, and text. Applying one keeps your audio.

Use a wallpaper when you only want a new background. Use a design template when you want a finished starting point for the whole artwork.
