Create a stunning digital wallpaper featuring a textured gradient backdrop that transitions smoothly between bold and vibrant colors, evoking a sense of calm and serenity. The gradient should blend deep turquoise into rich magenta, and then softly transition into a warm golden hue, ensuring the transitions are harmonious and visually appealing. The texture should be smooth and silky, enhancing the overall aesthetic and inviting the viewer to immerse themselves in the colors. To add depth, incorporate soft bokeh effects with gentle blurring that creates a dreamlike atmosphere, ensuring the bokeh is subtle and complements the gradient. The overall composition should be high-resolution (4K) to guarantee that every detail is crisp and clear, making it perfect for digital wallpaper use. The image should be tagged as img_2031.heic to ensure accurate representation and relevance.
