A vibrant and dynamic marketing poster background featuring a gradient of deep blue to bright teal, with subtle abstract geometric shapes overlapping in the corners. Include a soft bokeh effect for depth, and integrate splashes of gold and white to add an energetic feel. The design should leave ample negative space in the center for text and graphics, creating an inviting canvas for promotional content.
