Create a vibrant website mast background featuring an abstract design inspired by a celestial theme. Incorporate swirling galaxies, twinkling stars, and colorful nebulae in shades of deep navy, violet, and shimmering silver. The design should have a smooth gradient blending the colors, with a soft bokeh effect to add depth. Ensure there's a subtle texture to the background, giving it a cosmic and ethereal feel, while leaving ample negative space in the center for text or logos.
