Level-up Achievement Badge Sticker Prompts for Vector Design

Create a series of clean vector-style badge illustrations for ‘Level-up achievement’ icons. Each prompt should specify a high-contrast, no shading or gradients, pure white background, perfect for die-cut stickers. Use placeholder text [BadgeTitle] for badge labels and [DecorativeElements] for embellishments. Ensure each design exudes a sense of achievement, with bold lines and crisp details, suitable for high-quality printable stickers.
