Minimal Code Window Sticker Design Prompts

Create a series of clean, vector-style phone case sticker designs centered on minimal code window aesthetics. Maintain high contrast black outlines on a white background, avoid shading and gradients, and include a placeholder [CodeText] for customizing code snippets. The designs should be versatile, sleek, and easily die-cut, with focus on simplicity and clarity suitable for tech-savvy audiences or coding enthusiasts.
