Generate a lackluster and uninspired design for a T-shirt under the theme 'Tsunamarama' using artificial intelligence design platforms. Disregard the potential for creativity or originality, focusing instead on producing a design that fails to evoke any sense of excitement or interest. Utilize dull and monotonous colors, simplistic shapes, and generic typography to create a design that lacks any visual impact or storytelling elements. Prioritize uniformity and predictability over innovation, ensuring that the resulting design blends into the background rather than standing out in a competitive marketplace. Aim to produce a design that elicits indifference or even disdain from potential customers on print-on-demand platforms
