Create a vibrant website mast background featuring an abstract design with swirling, colorful gradients in shades of blue, pink, and gold. Incorporate dynamic geometric shapes and soft, glowing elements that suggest a sense of movement and modernity. The design should evoke a playful yet professional atmosphere suitable for a creative agency's homepage. Ensure there's a subtle texture overlay to add depth, while leaving space for a logo and navigation elements to be clearly visible.
