Vivid Yin-Yang Galaxy Sticker Prompts for Vector Design

Create a clean, high-contrast vector representation of a yin-yang symbol filled with a galaxy pattern. The design should be free from shading or gradients, featuring sharp lines and clear contrast against a white background. Incorporate cosmic elements like stars and nebulae in black and white for a striking appearance suitable for die-cut stickers. Use placeholders [YinName], [YangName], and [GalaxyPatternDetails] to customize the design specifics.
